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
- 5 - PCI, 33MHz
- 1 - PCI_F, 33MHz free running
- 1 - USB, 48MHz
- 1 - REF, 14.318MHz
- 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
- 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.
- Meets PCIEX <85ps cycle-to-cycle jitter for SRC[11:1]
- Single-ended programmable slew rate control for RFI reduction
Description
9ERS3165 follows Intel CK505 Yellow Cover specification. This clock synthesizer provides a single chip solution for Intel processors and Intel based systems. 9ERS3165 is driven with a 14.318MHz crystal. It also provides a tight ppm accuracy output for Serial ATA and PCI-Express support.
