The SiT3808 is a flexible LVCMOS/LVTTL compatible voltage-controlled oscillator (VCXO). Its programmable architecture enables any combination of frequency (from 1 to 80 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). The benefits are: superior pull range linearity and tuning slope consistency (Kv), 10 times better than quartz crystal VCXOs, which simplify PLL and clock synchronization design. The SiT3808 is an ideal replacement for legacy quartz devices due to its footprint and control voltage compatibility.
