ICS9LPR501_09 Datasheet, PDF (1/21 Pages) Integrated Device Technology – 64-PIN CK505 W/FULLY INTEGRATED VOLTAGE REGULATOR

Datasheet
64-PIN CK505 W/FULLY INTEGRATED VOLTAGE
REGULATOR
ICS9LPR501
Recommended Application:
CK505 compliant clock with fully integrated voltage
regulator, PCIe Gen 1 compliant
Output Features:
• 2 - CPU differential low power push-pull pairs
• 10 - SRC differential low power push-pull pairs
• 1 - CPU/SRC selectable differential low power push-pull
pair
• 1 - SRC/DOT selectable differential low power push-pull
pair
• 5 - PCI, 33MHz
• 1 - PCI_F, 33MHz free running
• 1 - USB, 48MHz
• 1 - REF, 14.318MHz
Key Specifications:
• CPU outputs cycle-cycle jitter < 85ps
• SRC output cycle-cycle jitter < 125ps
• PCI outputs cycle-cycle jitter < 250ps
• +/- 100ppm frequency accuracy on CPU & SRC
clocks
Features/Benefits:
• Does not require external pass transistor for voltage
regulator
• Supports spread spectrum modulation, default is 0.5%
down spread
• Uses external 14.318MHz crystal, external crystal
load caps are required for frequency tuning
• One differential push-pull pair selectable between
SRC and two single-ended outputs

1. FS_LA and FS_LB are low-threshold inputs.Please see V_{IL_FS} and V_{IH_FS} specifications in
the Input/Supply/Common Output Parameters Table for correct values.
Also refer to the Test Clarification Table.
2. FS_LC is a three-level input. Please see the V_{IL_FS} and V_{IH_FS}
specifications in the Input/Supply/Common Output Parameters Table for correct values.
