The SiT3809 is a highly flexible high-frequency MEMS voltage-controlled oscillator (VCXO) with LVCMOS output. This device supports any combination of frequencies (80.000001 to 220 MHz), voltage (1.8 V; 2.5 V to 3.3 V), pull range (±25 ppm to ±1600 ppm) and package (2520, 3225, 5032, 7050). It provides superior pull range linearity and tuning slope consistency (Kv), 10 times better than quartz VCXOs, which results in a simpler PLL and clock synchronization design. The SiT3809 is 100% compatible with legacy quartz devices in footprint and control voltage and therefore replaces crystal VCXO oscillators without any design changes.
