- Selectable PLL bandwidth; minimizes jitter peaking in downstream PLLs
- Spread spectrum compatible; tracks spreading input clock for low EMI
- Cycle-to-Cycle jitter <50ps
- Output-to-Output skew <65 ps
- Input-to-Output delay variation <50ps
- PCIe Gen 3 phase jitter <1.0ps RMS
- QPI/UPI 9.6GT/s 12UI phase jitter <0.2ps RMS
Description
The 9ZXL0831 is a low-power 8-output differential buffer that meets all the performance requirements of the Intel DB800ZL specification. It is suitable for PCI Express Gen 1/2/3 or QPI/UPI applications and uses fixed external feedback to maintain low drift for demanding QPI/UPI applications.
