SiTime Corporation Super-TCXOs SiT5155ACCFK-33VT-20.000000

The SiT5155 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 from -40°C to +105°C, supports supply voltages of 2.5 V, 2.8 V, 3.0 V, or 3.3 V, and offers a clipped sinewave output at 20.000000 MHz. The device features on-chip power regulators that eliminate the need for an external LDO, and provides digital frequency pulling via I²C with a maximum pull range of ±3200 ppm and resolution down to 5 ppt. It is RoHS and REACH compliant, with no activity dips or micro jumps, and resists vibration, shock, and board bending.
