SiT5503 Overview
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. SiT5503 is uniquely positioned for high reliability tele, edge networking, IEEE 1588 PTP, and optical transport applications.
SiT5503 Key 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 need for external LDOs
