SiTime Corporation Super-TCXOs SiT5358ANCFS-33VT-10.245000

The SiT5358 is a precision MEMS Super-TCXO offering ±50 ppb frequency stability from -40°C to 105°C, with a 5.0 mm × 3.2 mm ceramic package. It supports output frequencies from 1 MHz to 60 MHz in 1 Hz steps and provides a VCTCXO configuration with voltage-controlled frequency adjustment. The device integrates on-chip regulators to eliminate the need for an external LDO and delivers ±1 ppb/°C typical frequency slope, 1.5e-11 ADEV at 10-second averaging, and resistance to environmental stressors including vibration, shock, and electromagnetic interference. It operates on 2.5 V, 2.8 V, 3.0 V, or 3.3 V supply voltages and offers LVCMOS or clipped sinewave output formats.
