描述
The 9ZX21901C is an Intel DB1900Z differential buffer suitable for PCI Express Gen 1-2-3 or QPI applications. The 9ZX21901C has a fixed external feedback path. See the 9ZX21901B for an adjustable external feedback path.
特性
- 19 - 0.7V HCSL differential output pairs
- Fixed external feedback path
- Phase jitter: PCIe Gen3 < 1ps rms
- Phase jitter: PCIe Gen2 < 3.1ps rms
- Phase jitter: PCIe Gen1 < 86ps peak to peak
- Phase jitter: QPI 9.6GT/s < 0.2ps rms
- PLL or bypass mode
- PLL can de-jitter incoming clock
- 9 selectable SMBus addresses
- 8 OE# pins
- 100MHz or 133MHz PLL mode operation for PCIe and QPI applications
- Selectable PLL bandwidth minimizes jitter peaking in downstream PLLs
- Spread spectrum compatible
