描述
The 9LRS4206 is a low-power CK505-compliant clock specification. This clock synthesizer provides a single-chip solution for Intel processors and Intel chipsets. The 9LRS4206 is driven with a 14.318MHz crystal.
特性
- Supports tight ppm accuracy clocks for Serial-ATA and PCIEX
- Supports programmable spread percentage and frequency
- Uses external 14.318MHz crystal, external crystal load caps are required for frequency tuning
- Low power differential clock outputs (No 50Ω resistor to GND needed)
- Integrated 33Ω series resistor on all differential outputs
- Meets PCIEX Gen2 Specification
- CPU outputs cycle-cycle jitter < 85ps
- PCIEX outputs cycle-cycle jitter < 125ps
- SATA outputs cycle-cycle jitter < 125ps
- ±100ppm frequency accuracy on CPU, PCIEX, and SATA clocks
- ±100ppm frequency accuracy on USB clocks
