SiT5155 - Super-TCXO

Description

The SiT5155 is a ±0.5 ppm MEMS Super-TCXO that is engineered for high reliability, GNSS-based precision positioning and timing applications.

Features

  • 12 frequencies from 10 MHz to 40 MHz.
  • Factory programmable options for short lead time.
  • Best dynamic stability under airflow, thermal shock.
  • ±0.5 ppm stability across temperature.
  • ±15 ppb/°C typical frequency slope (ΔF/ΔT).
  • -40°C to +105°C operating temperature.
  • No activity dips or micro jumps.
  • Resistant to shock, vibration and board bending.
  • On-chip regulators eliminate the need for external LDOs.
  • Digital frequency pulling (DCTCXO) via I2C.
