9LRS3165BGLFT集成電路（IC）的應用特定時鐘/定時規(guī)格書PDF中文資料

Recommended Application:

CK505 compatible clock with fully integrated voltage regulator and

Internal series resistor on differential outputs

Output Features:

? 2 - CPU differential low power push-pull pairs

? 9 - 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

? Integrated 33ohm series resistors on differential outputs,

Zo=50Ω

? Supports spread spectrum modulation, default is 0.5 down

spread

? Uses external 14.318MHz crystal, external crystal load caps

are required for frequency tuning

? Selectable between one SRC differential push-pull pair and

two single-ended outputs

? Meets PCIEX Gen2 specification on dedicated SRC outputs.

Muxed SRC outputs meet PCIEX Gen1 specification, except

SRC1.

? Single-ended programmable slew rate control for RFI

reduction

? Meets PCIEX
