841608 Description
The 841608 is an optimized PCIe and sRIO clock generator. The device uses a 25MHz parallel crystal to generate 100MHz and 125MHz clock signals, replacing solutions requiring multiple oscillator and fanout buffer solutions. The device has excellent phase jitter (< 1ps rms) suitable to clock ponents requiring precise and low-jitter PCIe or sRIO or both clock signals.
841608 Key Features
- Eight HCSL outputs: configurable for PCIe (100MHz) and sRIO
- Selectable crystal oscillator interface, 25MHz, 18pF parallel
- Supports the following output frequencies: 100MHz or 125MHz
- VCO: 500MHz
- PLL bypass and output enable
- PCI Express (2.5 Gb/S) and Gen 2 (5 Gb/s) jitter pliant
- RMS phase jitter at 125MHz, using a 25MHz crystal
- 20MHz): 0.37ps (typical)
- Full 3.3V operating supply
- 40°C to 85°C ambient operating temperature
