1 to 80 MHz, ±5 ppm (VC)TCXO


The SiT5001 is a flexible MEMS TCXO with LVCMOS output and voltage-controlled frequency tuning. This device supports any combination of the following features: frequency (up to 80 MHz), voltage (1.8 V, 2.5 V-3.3 V), stability (±5 ppm), pull range (±12.5 ppm to ±50 ppm) and 4-pin packages (2520, 3225, 5032, 7050). It provides superior shock and vibration resistance, and high reliability.
