SiTime Corporation Super-TCXOs SiT5157AE-FD333IB-100.000000

The SiT5157 is a 60 MHz to 220 MHz MEMS Super-TCXO with ±0.5 ppm to ±2.5 ppm frequency stability, designed for high-reliability telecom, wireless, and precision GNSS applications. It operates from -40°C to +105°C and features LVCMOS output with supply voltages of 2.5 V, 2.8 V, 3.0 V, or 3.3 V. The device is housed in a 5.0 mm × 3.2 mm package and integrates on-chip regulators to eliminate the need for external LDOs. It supports digital frequency pulling via I2C with up to ±3200 ppm range and 5 ppt resolution, and meets RoHS and REACH compliance. No activity dips or micro jumps are present. For aerospace and defense, SiTime recommends the Endura™ SiT5147 instead.
