6pin

The SiT5000 is a highly flexible high performance Voltage Controlled, Temperature Compensated MEMS Oscillator ( MEMS VCTCXO) with LVCMOS/LVTTL/HCMOS compatible output. This device supports a list of 26 standard frequencies along any combination of voltage (1.8V, 2.5V-3.3V), stability (±1.5PPM to ±5PPM) 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.
