Overview
Description
The 9ZX21501 is an Intel™ DB1900Z-compatible differential buffer suitable for PCI Express Gen3 or QPI applications. The part is backwards compatible to PCIe Gen1 and Gen2. A fixed external feedback maintains low drift for critical QPI applications.
Features
- Fifteen 0.7V HCSL differential output pairs
- 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
- Supports zero delay buffer mode and fanout mode
- Bandwidth programming available
- 9 selectable SMBus addresses
- 7 OE# pins; 90–140MHz operation in PLL mode
- 33–150MHz operation in Bypass mode
