LVCMOS CMEMS Programmable Oscillator Series

Features

Si501/2/3/4

Description

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.

Applications:

General purpose microcontrollers, industrial control, IP

cameras, surveillance systems, metering, home and office automation,

security systems, sleep clocking, 10/100 Ethernet/EtherCAT, SPI, SAS3.0 /

SATA3.0, PCIe ref clock, NVMe, HDD, SSD, hybrid storage, DDR3/3L,

USB2.0, USB OTG/2.0, M2M, HDMI

Not recommended:

Wi-Fi, Bluetooth, USB 3.0, Gigabit Ethernet

Ordering Guide Notes:

1. Series termination resistor (R

– see Apps Circuits section) is recommended for this configuration.

2. Series termination resistor (R

) is not needed for this configuration. Output impedance is 50Ω for the indicated supply condition.

3. Series termination resistor (R

) 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.

6. The Si502 OE pin has three (3) states: OE High = Freq 1; OE Weak High = Freq 2; OE Low is configurable.
