Pin Configuration
Recommended Application:
Low Power CK410M Compliant Main Clock
Output Features:
2 - 0.7V push-pull differential CPU pairs
5 - 0.7V push-pull differential PCIEX pairs
1 - 0.7V push-pull differential SATA pair
1 - 0.7V push-pull differential CPU/PCIEX selectable pair
1 - 0.7V push-pull differential 27MHz/LCDCLK/PCIEX
selectable pair
4 - PCI (33MHz)
2 - PCICLK_F, (33MHz) free-running
1 - USB, 48MHz
2 - REF, 14.318MHz
Key Specifications:
CPU outputs cycle-cycle jitter < 85ps
PCIEX outputs cycle-cycle jitter < 125ps
SATA outputs cycle-cycle jitter < 125ps
PCI outputs cycle-cycle jitter < 500ps
+/- 100ppm frequency accuracy on CPU, PCIEX and
SATA clocks
+/- 100ppm frequency accuracy on USB clocks
Features/Benefits:
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
PEREQ# pins to support PCIEX power management.
Low power differential clock outputs (No 50W resistor
to GND needed)
