SiTime Corporation Super-TCXOs SiT5155AECFK-30VT-25.000000

The SiT5155 is a ±0.5 ppm MEMS Super-TCXO designed for GNSS/GPS precision 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 a 2.5 V, 2.8 V, 3.0 V, or 3.3 V supply, and offers a clipped sinewave output with digital frequency pulling via I²C, up to ±3200 ppm. It integrates on-chip power regulators to eliminate external LDOs, and resists shock, vibration, and electromagnetic interference. The SiT5155AECFK-30VT-25.000000 variant is a VCTCXO configuration with a 3.0 V supply and 25 MHz output frequency. This part is part of a broader family of factory-programmable devices for GNSS, microwave backhaul, and test equipment applications.
