SiTime Corporation Super-TCXOs SiT5155AICFK-25VT-40.000000

The SiT5155 is a ±0.5 ppm MEMS Super-TCXO designed for precision GNSS/GPS timing applications, housed in a 5.0 mm × 3.2 mm package with LVCMOS or clipped sinewave output. It operates from -40°C to +105°C, offers on-chip power regulators to eliminate external LDOs, and supports digital frequency pulling via I2C with a pull range up to ±3200 ppm. The device is RoHS and REACH compliant, and features stability of ±0.5 ppm across temperature with a typical frequency slope of ±15 ppb/°C. It prohibits activity dips and micro jumps, and resists shock, vibration, and board bending. Output frequency for this variant is 40.000000 MHz with a 2.5 V supply and VCTCXO configuration.
