SiTime Corporation Super-TCXOs SiT5503ABCWW-33E0-10.000000

The SiT5503 is a 1 MHz to 60 MHz Elite X™ MEMS precision oscillator designed for Stratum 3E applications, offering ±5 ppb frequency stability from -40°C to 95°C. It features a 7.0 mm x 5.0 mm ceramic package, integrates on-chip power regulators to eliminate external LDOs, and supports LVCMOS or clipped sinewave outputs at 2.5 V, 2.8 V, 3.0 V, or 3.3 V. The device provides digital frequency control up to ±3200 ppm, resists dynamic stressors such as vibration, shock, and thermal transients, and is RoHS and REACH compliant. It is optimized for telecom, optical transport, IEEE 1588 PTP, and precision GNSS systems.
