SiTime Corporation Super-TCXOs SiT5357AC-FQA25IY-125.000000

The SiT5357 is a 60 MHz to 220 MHz precision Super-TCXO with ±100 ppb frequency stability across temperature and a typical frequency slope of ±1 ppb/°C, designed for Stratum 3 telecom, wireless, and GNSS applications. It operates from -40°C to +105°C, features LVCMOS output, and integrates on-chip regulators to eliminate the need for an external LDO. The device is available in a 5.0 mm × 3.2 mm package and supports factory-programmable frequencies in 1 Hz steps, with supply voltages of 2.5 V, 2.8 V, 3.0 V, or 3.3 V. The SiT5357AC-FQA25IY-125.000000 variant specifies a 125 MHz output frequency, 2.5 V supply, industrial temperature range, and an output enable pin, consistent with the series' TCXO configuration and RoHS-compliant, Pb-free construction.
