High-performance, programmable MEMS VCXO, 1 to 80 MHz

Numéro de référence fabricant :


Fabricant SiTime


Description :

The SiT3808 is the most flexible LVCMOS/LVTTL compatible Voltage Controlled Oscillator (VCXO) on the market. The device supports any combination of frequencies (up to 80 MHz), voltage (1.8V, 2.5V to 3.3V), 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 crystal VCXOs, thereby simplifying PLL and clock synchronization design.
