特性
- LP-HCSL outputs; eliminate 16 resistors, save 27mm² of area
- PCIe Gen 1–5 compliance
- 8 OE# pins; hardware control of each output
- Selectable PLL BW; minimizes jitter peaking in cascaded PLL topologies
- Hardware/SMBus control of PLL bandwidth and bypass; change mode without power cycle
- Spread spectrum compatible; tracks spreading input clock for EMI reduction
- 100MHz and 133.33MHz PLL mode; UPI and legacy QPI support
- 6mm ×6 mm 48-VFQFPN package; small board footprint

描述
The 9ZXL0831E is a second-generation enhanced performance DB800ZL differential buffer. The part is a pin-compatible upgrade to the 9ZXL0831A while offering a much-improved phase jitter performance. A fixed external feedback maintains low drift for critical QPI/UPI applications.
