The SiT5157 is a 60 MHz to 220 MHz MEMS Super-TCXO with ±0.5 ppm to ±2.5 ppm frequency stability across -40°C to +105°C, designed for high-reliability telecom, wireless, and precision GNSS applications. It features a 5.0 mm × 3.2 mm package, LVCMOS output, and operates at 3.3 V supply voltage. The device includes on-chip regulators to eliminate external LDOs, supports digital frequency pulling via I2C with up to ±3200 ppm range and 5 ppt resolution, and is RoHS and REACH compliant. It exhibits ±15 ppb/°C typical frequency slope and is resistant to shock, vibration, and thermal perturbation.
