IQMS-500, -510, -520, -530 SERIES MEMS OSCILLATORS
ISSUE 1; 29 APRIL 2009 - RoHS 2002/95/EC
Description
A series of factory programmable SMD plastic packaged
oscillators based on MEMS technology with high
performance and low jitter
Package Outlines
7 x 5mm (IQMS-500, 501, 502, 503)
5 x 3.2mm (IQMS-510, 511, 512, 513)
3.2 x 2.5mm (IQMS-520, 521, 522, 523)
2.5 x 2mm (IQMS-530, 531, 532, 533)
Frequency Range
1 to 110MHz
Output Compatibility & Load
Tri-state / Standby CMOS
Drive Capability 15pF max
Frequency Stabilities
±25ppm, ±30ppm, ±50ppm, ±100ppm over the operating
temperature range (inclusive of supply voltage variation, load
variation, ageing, shock and vibration)
Operating Temperature Ranges
–20 to 70°C (IQMS-500, 510, 520, 530 series)
–40 to 85°C (IQMS-500I, 510I, 520I, 530I series)
Storage Temperature Range
–55 to 125°C
Tri-state Operation (TS option)
Logic ‘1’ (
>70%Vs) to pad 1 enables oscillator output
Logic ‘0’ (
<30%Vs) to pad 1 disables oscillator output;
when disabled the oscillator output goes to the high
impedance state
No connection to pad ‘1’ enables oscillator output
Standby (ST option)
Logic ‘1’ (
>70%Vs) to pad 1 enables oscillator output
Logic ‘0’ (
<30%Vs) to pad 1 oscillator output is low level;
oscillation stops ( output weakly pulled down )
No connection to pad ‘1’ enables oscillator output
Standby Current: 10
mA max
