SiTime Corporation Super-TCXOs SiT5155AECFK-33E0-20.000000

The SiT5155AECFK-33E0-20.000000 is a ±0.5 ppm MEMS super-TCXO designed for GNSS/GPS precision timing applications, housed in a 5.0 mm × 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 features on-chip power regulators that eliminate the need for an external LDO, supports LVCMOS output at 3.3 V, and provides digital frequency control via I²C with a pull range of ±150 ppm. It is RoHS and REACH compliant, with no activity dips or micro jumps, and resists shock, vibration, and board bending.
