The 9ZXL0631E is a second-generation, enhanced-performance DB800ZL derivative. The part is a pin-compatible upgrade to the 9ZXL0631A, while offering a much improved phase jitter performance. A fixed external feedback maintains low drift for critical QPI/UPI applications.
- LP-HCSL outputs; eliminate 12 resistors, save 20mm² of area
- 6 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 PLL Mode; UPI support
- 5 × 5 mm 40-VFQFPN package; small board footprint
