SiT5503 - Precision Oscillator

Description

The SiT5503 is a Stratum 3E MEMS precision oscillator optimized for ±5 ppb stability from -40°C to 95°C.

Engineered for exceptional dynamic performance, it is ideal for replacing larger and less robust quartz OCXOs.

Features

  • Any frequency from 1 MHz to 60 MHz in 1 Hz steps.
  • Factory programmable options for low lead time.
  • Best dynamic stability under airflow, thermal shock.
  • ±5 ppb stability over temperature, -40°C to 95°C.
  • ±0.3 ppb/°C typical frequency slope (ΔF/ΔT).
  • 1.5e-11 ADEV at 10 second averaging time.
  • Digital frequency control up to ±3200 ppm.
  • No activity dips or micro jumps.
  • Resistant to shock, vibration and board bending.
  • On-chip regulators eliminate the nee.
