Si501/2/3/4
LVCMOS CMEMS® Programmable Oscillator Series
Description
Features
The Si501/2/3/4 CMEMS programmable oscillator series combines
standard CMOS + MEMS in a single, monolithic IC to provide high-quality
and high-reliability oscillators. Each device is specified for guaranteed
performance across voltage, process, temperature, shock, vibration and
aging for 10 years. More information on CMEMS available at
www.silabs.com/cmems.

Ordering Guide Notes:
1. Series termination resistor (RS – see Apps Circuits section) is recommended for this configuration.
2. Series termination resistor (RS) is not needed for this configuration. Output impedance is 50Ω for the indicated supply condition.
3. Series termination resistor (RS) is not needed for this configuration. Reduced EMI setting.
4. 3.2 x 5 mm package is delivered as 3.2 x 4 mm and accommodates the industry-standard 3.2 x 5 mm footprint.
5. Select option to support maximum anticipated frequency needed.
