SiTime Corporation Super-TCXOs SiT5155AECFK-28E0-16.368000

The SiT5155 is a ±0.5 ppm MEMS Super-TCXO designed for high-reliability GNSS/GPS timing applications, housed in a 5.0 mm x 3.2 mm package. It operates across -40°C to +105°C with frequency stability of ±0.5 ppm over temperature and a typical frequency slope of ±15 ppb/°C. The device supports 2.8 V supply voltage, LVCMOS output, and includes on-chip regulators to eliminate external LDOs. It features digital frequency pulling via I2C with a pull range up to ±3200 ppm and resolution down to 5 ppt. The part is RoHS and REACH compliant, with no activity dips or micro jumps, and is resistant to shock, vibration, and board bending.
