MEMS Differential Oscillators | SiT9507 Series
Product Introduction
SiT9507 is SITIME's flagship ultra-low jitter differential MEMS oscillator for high-performance network infrastructure. Typical phase jitter: 29 fs RMS (12 kHz–20 MHz) — meeting 112G/224G SerDes and optical module timing demands. Industry's smallest 2.0×1.6 mm differential MEMS package saves 50% PCB space vs quartz. 4th-gen MEMS delivers superior vibration, EMI, and power noise immunity from -40°C to +105°C. Supports LVPECL, LVDS, HCSL, low-power HCSL; 1.8–3.63V; ±20 to ±50 ppm stability; 16 standard frequencies (100–625 MHz). Available through YQM ELECTRONICS (YQM).
Core Advantages
- 29 fs RMS Jitter: Industry-best 29 fs ensures wider eye openings and lower BER for 112G/224G SerDes.
- 4th-Gen MEMS: 20× better shock/vibration resistance than quartz. No activity dips, no micro-jumps.
- Smallest Package: 2.0×1.6 mm — 50% smaller than quartz. Integrated termination resistors.
- Multi-Format + 16 Freq: LVPECL/LVDS/HCSL/low-power HCSL. 100/156.25/312.5/625 MHz + 12 more.
- Stable Semiconductor Supply: Silicon MEMS process — consistent quality, predictable lead times.
