Overview
Description
The 932SQ428 is a main clock synthesizer for Romley-generation Intel based server platforms. The 932SQ428 is driven with a 25 MHz crystal for maximum performance. It generates CPU outputs of 100MHz.
Features
- 2 - HCSL Non-Spread SAS outputs
- 3 - HCSL SRC outputs - can be used as CPU@100M
- 1 - HCSL DOT96 output
- 1 - 3.3V 48M output
- 5 - 3.3V PCI outputs
- 1 - 3.3V 14.318M output
- 0.5% down spread capable on SRC/PCI outputs
- Lower EMI
- 48-pin MLF package
- Space Savings
- Cycle to cycle jitter: SRC/NS_SAS < 50ps
- Phase jitter: PCIe Gen2 <3ps rms
- Phase jitter: PCIe Gen3 <1ps rms
- Phase jitter: QPI 9.6GB/s <0.2ps rms
- Phase jitter: NS-SAS <0.4ps rms using raw phase data
- Phase jitter: NS-SAS <1.3ps rms using Clk Jit Tool 1.6.3
