SiT5004: Ultra-Stable, High Frequency MEMS VCTCXO (80-220 MHz, 0.5 PPM)

E-mail Print
4pin MEMS VCTCXO is pin compatible with crystal TCXO

The SiT5004 is the most flexible LVCMOS/LVTTL/HCMOS compatible, ultra-stable MEMS VCTCXO (Voltage Controlled, Temperature Compensated Oscillator) solution in the market. This device supports any combination of the following features: frequency (80.000001 - 220MHz), voltage (1.8V, 2.5V-3.3V), stability (±0.5PPM), pull range (±12.5PPM to ±50PPM) and packages (3225, 5032, 7050). It provides superior shock and vibration resistance, and 2 FIT reliability that is 10 times better than crystal VCTCXO and TCXO oscillators and is ideal for high reliability applications in telecom, networking, wireless and embedded. SiTime's MEMS devices are 100% compatible with legacy quartz crystal VCTCXO and TCXO oscillators in footprint and package, and replace these devices without any design changes.
