The SiT3809 is a LVCMOS/LVTTL compatible voltage-controlled oscillator (VCXO) that supports any combination of the following specifications: frequency (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, or7050). It provides incredible pull range linearity and tuning slope consistency (Kv), 10 times better than quartz crystal VCXOs, which simplifies PLL and clock synchronization design. The SiT3809 is also footprint compatible with quartz VCXOs, making it an easy drop-in replacement for legacy devices.
