- 2
- PCICLK_F, (33MHz) free-running
- 1
- USB, 48MHz
- 1
- DOT, 96MHz, 0.7V current differential pair
- 1
- REF, 14.318MHz
- 1
- 0.7V current-mode differential LCD/SRC selectable pair.
- PCI outputs cycle-cycle jitter < 500ps
- +/- 300ppm frequency accuracy on CPU & SRC clocks
- +/- 100ppm frequency accuracy on USB clocks Features
/Benefits:
- Supports tight ppm accuracy clocks for Serial-ATA and
- Supports programmable spread percentage and frequency
- Uses external 14.318MHz crystal, external crystal load caps are required for frequency tuning
- Supports undriven differential CPU, SRC pair in PD# for power management.
- CLKREQ pins to support SRC power management.
Key Specifications:
- CPU outputs cycle-cycle jitter < 85ps
- SRC outputs cycle-cycle jitter < 125ps
