SiT5001: High Performance MEMS VCTCXO (1-80 MHz, ±1 to ±5 PPM)

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

The SiT5001 is the most flexible LVCMOS/LVTTL/HCMOS compatible, MEMS VCTCXO (Voltage Controlled, Temperature Compensated Oscillator) solution in the market. This device supports any combination of the following features: frequency (up to 80MHz), voltage (1.8V, 2.5V-3.3V), stability (±1PPM to ±5PPM), pull range (±12.5PPM to ±50PPM) and 4-pin packages (2520, 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.
