ICS841402I Overview
The ICS841402I is an optimized PCIe and sRIO clock generator. The device uses a 25MHz parallel resonant crystal to generate 100MHz, 125MHz, 200MHz and 400MHz clock signals, replacing solutions requiring multiple oscillator and fanout buffer solutions. The device has excellent phase jitter suitable to clock ponents requiring precise and low jitter PCIe, sRIO or both clock signals.
ICS841402I Key Features
- Two 0.7V differential HCSL outputs: configurable for PCIe
