NVT2001; NVT2002 Bidirectional voltage level translator for open-drain and push-pull applications Rev. 3 -- 26 April 2012 Product data sheet 3 1. General description The NVT2001/02 are bidirectional voltage level translators operational from 1.0 V to 3.6 V (Vref(A)) and 1.8 V to 5.5 V (Vref(B)), which allow bidirectional voltage translations between 1.0 V and 5 V without the need for a direction pin in open-drain or push-pull applications. Bit widths ranging from 1-bit or 2-bit are offered for level translation application with transmission speeds < 33 MHz for an open-drain system with a 50 pF capacitance and a pull-up of 197 . When the An or Bn port is LOW, the clamp is in the ON-state and a low resistance connection exists between the An and Bn ports. The low ON-state resistance (Ron) of the switch allows connections to be made with minimal propagation delay. Assuming the higher voltage is on the Bn port when the Bn port is HIGH, the voltage on the An port is limited to the voltage set by VREFA. When the An port is HIGH, the Bn port is pulled to the drain pull-up supply voltage (Vpu(D)) by the pull-up resistors. This functionality allows a seamless translation between higher and lower voltages selected by the user without the need for directional control. When EN is HIGH, the translator switch is on, and the An I/O are connected to the Bn I/O, respectively, allowing bidirectional data flow between ports. When EN is LOW, the translator switch is off, and a high-impedance state exists between ports. The EN input circuit is designed to be supplied by Vref(B). To ensure the high-impedance state during power-up or power-down, EN must be LOW. All channels have the same electrical characteristics and there is minimal deviation from one output to another in voltage or propagation delay. This is a benefit over discrete transistor voltage translation solutions, since the fabrication of the switch is symmetrical. The translator provides excellent ESD protection to lower voltage devices, and at the same time protects less ESD-resistant devices. 2.

Application design-in information The NVT2001/02 can be used in level translation applications for interfacing devices or systems operating at different interface voltages with one another. The NVT2001/02 is ideal for use in applications where an open-drain driver is connected to the data I/Os. The NVT2001/02 can also be used in applications where a push-pull driver is connected to the data I/Os. 7.1 Enable and disable The NVT20xx has an EN input that is used to disable the device by setting EN LOW, which places all I/Os in the high-impedance state.

All rights reserved. 6 of 22 NVT2001; NVT2002 NXP Semiconductors Bidirectional voltage level translator 7.2 Bidirectional translation For the bidirectional clamping configuration (higher voltage to lower voltage or lower voltage to higher voltage), the EN input must be connected to VREFB and both pins pulled to HIGH side Vpu(D) through a pull-up resistor (typically 200 k). This allows VREFB to regulate the EN input. A filter capacitor on VREFB is recommended. The master output driver can be totem pole or open-drain (pull-up resistors may be required) and the slave device output can be totem pole or open-drain (pull-up resistors are required to pull the Bn outputs to Vpu(D)). However, if either output is totem-pole, data must be unidirectional or the outputs must be 3-stateable and be controlled by some direction-control mechanism to prevent HIGH-to-LOW contentions in either direction. If both outputs are open-drain, no direction control is needed. The reference supply voltage (Vref(A)) is connected to the processor core power supply voltage. When VREFB is connected through a 200 k resistor to a 3.3 V to 5.5 V Vpu(D) power supply, and Vref(A) is set between 1.0 V and (Vpu(D) 1 V), the output of each An has a maximum output voltage equal to VREFA, and the output of each Bn has a maximum output voltage equal to Vpu(D). 7.3 Sizing pull-up resistor The pull-up resistor value needs to limit the current through the pass transistor when it is in the ON state to about 15 mA. This ensures a pass voltage of 260 mV to 350 mV. If the current through the pass transistor is higher than 15 mA, the pass voltage also is higher in the ON state. To set the current through each pass transistor at 15 mA, the pull-up resistor value is calculated as: V pu D - 0.35 V R PU = ------------------------------------0.015 A Table 5 summarizes resistor reference voltages and currents at 15 mA, 10 mA, and 3 mA. The resistor values shown in the +10 % column or a larger value should be used to ensure that the pass voltage of the transistor would be 350 mV or less. The external driver must be able to sink the total current from the resistors on both sides of the NVT20xx device at 0.175 V, although the 15 mA only applies to current flowing through the NVT20xx device.

Basically, the NVT20xx behaves like a wire with the additional characteristics of transistor device physics and should be capable of performing at higher frequencies if used correctly. Here are some guidelines to follow that will help maximize the performance of the device: * Keep trace length to a minimum by placing the NVT20xx close to the processor. * The trace length should have a time of flight less than half of the transition time to reduce ringing and reflections. * The faster the edge of the signal, the higher the chance for ringing. * The higher the drive strength (up to 15 mA), the higher the frequency the device can use. In a 3.3 V to 1.8 V direction level shift, if the 3.3 V side is being driven by a totem pole type driver no pull-up resistor is needed on the 3.3 V side. The capacitance and line length of concern is on the 1.8 V side since it is driven through the ON resistance of the NVT20xx. If the line length on the 1.8 V side is long enough there can be a reflection at the chip/terminating end of the wire when the transition time is shorter than the time of flight of the wire because the NVT20xx looks like a high-impedance compared to the wire. If the wire is not too long and the lumped capacitance is not excessive the signal will only be slightly degraded by the series resistance added by passing through the NVT20xx. If the lumped capacitance is large the rise time will deteriorate, the fall time is much less affected and if the rise time is slowed down too much the duty cycle of the clock will be degraded and at some point the clock will no longer be useful. So the principle design consideration is to minimize the wire length and the capacitance on the 1.8 V side for the clock path. A pull-up resistor on the 1.8 V side can also be used to trade a slower fall time for a faster rise time and can also reduce the overshoot in some cases. 7.3.1.1 Example maximum frequency Question -- We need to make the PLL area of a new line card backwards compatible and need to need to convert one GTL signal to LVTTL, invert it, and convert it back to GTL. The signal we want to convert is random in nature but will mostly be around 19 MHz with very long periods of inactivity where either a HIGH or LOW state will be maintained. The traces are 1 or 2 inches long with trace capacitance of about 2 pF per inch. Answer -- The frequency of the NVT20xx is limited by the capacitance of the part, the capacitance of the traces and the pull-up resistors used. The limiting case is probably the LOW-to-HIGH transition in the GTL to LVTTL direction, and there the use of the lowest acceptable resistor values will minimize the rise time delay. Assuming 50 pF capacitance and 220 resistance, the RC time constant is 11 ns (50 pF 220 ). With 19 MHz corresponding to 50 ns period the NVT20xx will support this application.

Performance curves tPLH up-translation is typically dominated by the RC time constant, i.e., CL(tot) RPU = 50 pF 197 = 9.85 ns, but the Ron CL(tot) = 50 pF 5 = 0.250 ns. tPHL is typically dominated by the external pull-down driver + Ron, which is typically small compared to the tPLH in an up-translation case. Enable/disable times are dominated by the RC time constant on the EN pin since the transistor turn off is on the order of ns, but the enable RC is on the order of ms. Fall time is dominated by the external pull-down driver with only a slight Ron addition. Rise time is dominated by the RPU CL. Skew time within the part is virtually non-existent, dominated by the difference in bond wire lengths, which is typically small compared to the board-level routing differences.

Soldering of SMD packages This text provides a very brief insight into a complex technology. A more in-depth account of soldering ICs can be found in Application Note AN10365 "Surface mount reflow soldering description". 14.1 Introduction to soldering Soldering is one of the most common methods through which packages are attached to Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides both the mechanical and the electrical connection. There is no single soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and Surface Mount Devices (SMDs) are mixed on one printed wiring board; however, it is not suitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and high densities that come with increased miniaturization. 14.2 Wave and reflow soldering Wave soldering is a joining technology in which the joints are made by solder coming from a standing wave of liquid solder. The wave soldering process is suitable for the following: * Through-hole components * Leaded or leadless SMDs, which are glued to the surface of the printed circuit board Not all SMDs can be wave soldered. Packages with solder balls, and some leadless packages which have solder lands underneath the body, cannot be wave soldered. Also, leaded SMDs with leads having a pitch smaller than ~0.6 mm cannot be wave soldered, due to an increased probability of bridging. The reflow soldering process involves applying solder paste to a board, followed by component placement and exposure to a temperature profile. Leaded packages, packages with solder balls, and leadless packages are all reflow solderable. Key characteristics in both wave and reflow soldering are: * * * * * * Board specifications, including the board finish, solder masks and vias Package footprints, including solder thieves and orientation The moisture sensitivity level of the packages Package placement Inspection and repair Lead-free soldering versus SnPb soldering 14.3 Wave soldering Key characteristics in wave soldering are: * Process issues, such as application of adhesive and flux, clinching of leads, board transport, the solder wave parameters, and the time during which components are exposed to the wave * Solder bath specifications, including temperature and impurities NVT2001_NVT2002 Product data sheet All information provided in this document is subject to legal disclaimers.

It is imperative that the peak temperature is high enough for the solder to make reliable solder joints (a solder paste characteristic). In addition, the peak temperature must be low enough that the packages and/or boards are not damaged. The peak temperature of the package depends on package thickness and volume and is classified in accordance with Table 10 and 11 Table 10. SnPb eutectic process (from J-STD-020C) Package thickness (mm) Package reflow temperature (C) Volume (mm3) < 350 350 < 2.5 235 220 2.5 220 220 Table 11.

Studies have shown that small packages reach higher temperatures during reflow soldering, see Figure 16.
