特性
- 8 - 0.7V low-power HCSL-compatible output pairs
- Low-power push-pull outputs; Save power and board space - no Rp
- Space-saving 48-pin VFQFPN package
- Fixed feedback path for 0ps input-to-output delay
- 8 OE# pins; hardware control of each output
- PLL or bypass mode; PLL can de-jitter incoming clock
- 100MHz or 133MHz PLL mode operation; supports PCIe and QPI applications
- 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
描述
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.
