19-2078; Rev 2; 10/02 1:10 Differential LVPECL/LVECL/HSTL Clock and Data Drivers The MAX9311/MAX9313 are low-skew, 1-to-10 differential drivers designed for clock and data distribution. These devices allow selection between two inputs. The selected input is reproduced at 10 differential outputs. The differential inputs can be adapted to accept singleended inputs by connecting the on-chip VBB supply to one input as a reference voltage. The MAX9311/MAX9313 feature low part-to-part skew (30ps) and output-to-output skew (12ps), making them ideal for clock and data distribution across a backplane or a board. For interfacing to differential HSTL and LVPECL signals, these devices operate over a +2.25V to +3.8V supply range, allowing high-performance clock or data distribution in systems with a nominal +2.5V or +3.3V supply. For differential LVECL operation, these devices operate from a -2.25V to -3.8V supply. The MAX9311 features an on-chip VBB reference output of 1.425V below the positive supply voltage. The MAX9313 offers an on-chip V BB reference output of 1.32V below the positive supply voltage. Both devices are offered in space-saving, 32-pin 5mm 5mm TQFP, 5mm x 5mm QFN, and industry-standard 32-pin 7mm x 7mm LQFP packages.

A 2:1 mux selects between the two differential inputs, CLK0, CLK0 and CLK1, CLK1. The 2:1 mux is switched by the single-ended CLKSEL input. A logic low selects the CLK0, CLK0 input. A logic high selects the CLK1, CLK1 input. The logic threshold for CLKSEL is set by an internal VBB voltage reference. The CLKSEL input can be driven to VCC and VEE or by a single-ended LVPECL/ LVECL signal. The selected input is reproduced at 10 differential outputs. For interfacing to differential HSTL and LVPECL signals, these devices operate over a +2.25V to +3.8V supply range, allowing high-performance clock or data distribution in systems with a nominal +2.5V or +3.3V supply. For differential LVECL operation, these devices operate from a -2.25V to -3.8V supply. The differential inputs can be configured to accept single-ended inputs when operating at approximately VCC VEE = +3.0V to +3.8V for the MAX9311 or VCC - VEE = +2.7V to +3.8V for the MAX9313. This is accomplished by connecting the on-chip reference voltage, VBB, to an input as a reference. For example, the differential CLK0, CLK0 input is converted to a noninverting, single-ended input by connecting VBB to CLK0 and connecting the single-ended input to CLK0. Similarly, an inverting input is obtained by connecting VBB to CLK0 and connecting the single-ended input to CLK0. With a differential input configured as single-ended (using V BB), the singleended input can be driven to VCC and VEE or with a single-ended LVPECL/LVECL signal. When a differential input is configured as a single-ended input (using VBB), the approximate supply range is VCC VEE = +3.0V to +3.8V for the MAX9311 and VCC - VEE = +2.7V to +3.8V for the MAX9313. This is because one of the inputs must be VEE + 1.2V or higher for proper operation of the input stage. VBB must be at least VEE + 1.2V because it becomes the high-level input when the other (single-ended) input swings below it. Therefore, minimum VBB = VEE + 1.2V. The minimum VBB output for the MAX9311 is VCC 1.525V and the minimum VBB output for the MAX9313 is VCC - 1.38V. Substituting the minimum VBB output for each device into VBB = VEE + 1.2V results in a minimum supply of 2.725V for the MAX9311 and 2.58V for the MAX9313. Rounding up to standard supplies gives the single-ended operating supply ranges of VCC - VEE = 3.0V to 3.8V for the MAX9311 and VCC - VEE = 2.7V to 3.8V for the MAX9313. When using the VBB reference output, bypass it with a 0.01F ceramic capacitor to VCC. If the VBB reference is not used, it can be left open. The VBB reference can source or sink 0.5mA, which is sufficient to drive two inputs. Use VBB only for inputs that are on the same device as the VBB reference. The maximum magnitude of the differential input from CLK_ to CLK_ is 3.0V or VCC - VEE, whichever is less. This limit also applies to the difference between any reference voltage input and a single-ended input. The differential inputs have bias resistors that drive the outputs to a differential low when the inputs are open. The inverting inputs (CLK0 and CLK1) are biased with a 75k pullup to VCC and a 75k pulldown to VEE. The noninverting inputs (CLK0 and CLK1) are biased with a 75k pulldown to VEE. The single-ended CLKSEL input does not have a bias resistor. If not driven, pull CLKSEL up or down with a 1kHz resistor (see Pin Description). Specifications for the high and low voltages of a differential input (VIHD and VILD) and the differential input voltage (VIHD - VILD) apply simultaneously (VILD cannot be higher than VIHD). Output levels are referenced to VCC and are considered LVPECL or LVECL, depending on the level of the VCC supply. With VCC connected to a positive supply and VEE connected to GND, the outputs are LVPECL. The outputs are LVECL when VCC is connected to GND and VEE is connected to a negative supply. A single-ended input of at least VBB 95mV or a differential input of at least 95mV switches the outputs to the V OH and V OL levels specified in the DC Electrical Characteristics table. Applications Information Supply Bypassing Bypass VCC to VEE with high-frequency surface-mount ceramic 0.1F and 0.01F capacitors in parallel as close to the device as possible, with the 0.01F value capacitor closest to the device. Use multiple parallel vias for low inductance. When using the VBB reference output, bypass it with a 0.01F ceramic capacitor to VCC (if the VBB reference is not used, it can be left open). Traces Input and output trace characteristics affect the performance of the MAX9311/MAX9313. Connect each signal of a differential input or output to a 50 characteristic impedance trace. Minimize the number of vias to prevent impedance discontinuities. Reduce reflections by maintaining the 50 characteristic impedance through connectors and across cables.
