SiT7204
120 to 600 MHz, ±0.1 to ±1 ppm Endura™ Ruggedized Differential LVDS Super-TCXO
The SiT7204 is a ruggedized differential LVDS ±0.10 to ±1 ppm precision MEMS Super-TCXO designed for high stability and low jitter applications and supports any frequency from 120 MHz to 600 MHz.
The SiT7204 combines SiTime’s MEMS technology with a low-noise digital PLL to deliver:
- Excellent jitter for high-speed communication
- Excellent dynamic stability in the presence of airflow and thermal excursions
- Extreme resistance to shock and vibration
The SiT7204 offers two device configurations for:
- TCXO with non-pullable output frequency
- DCTCXO enabling digital pulling of output frequency via an I2C/SPI interface with a resolution of 0.05 ppt (parts per trillion)
The SiT7204 can be factory programmed for stability, voltage, and digital pulling capability, eliminating long lead times and customization costs associated with quartz devices.
