SiTime Corporation Super-TCXOs SiT5155AECFK033IT-40.000000

The SiT5155 is a ±0.5 ppm MEMS Super-TCXO designed for high-reliability GNSS and GPS 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 supports LVCMOS or clipped sinewave outputs and integrates on-chip regulators to eliminate the need for an external LDO. It offers digital frequency pulling via I2C with a pull range up to ±3200 ppm and 5 ppt resolution. This variant is factory-programmed for 40.000000 MHz, 3.3 V supply, and industrial temperature range (-40°C to +85°C), with I2C address set to 0x03 and software-controlled output enable.
