9Z61195D Datasheet 19-Output DB1900Z Derivative

Manufacturer: Renesas

Datasheet Details

The 9Z61195D is a second-generation, enhanced-performance DB1900Z derivative differential buffer.

The part is a pin-compatible upgrade to the 9Z61195A, offering much improved phase jitter performance.

A fixed external feedback maintains low drift for critical QPI/UPI applications.

19-Output DB1900Z Derivative for PCIe Gen1–4 and UPI for Dell Servers 9Z61195D.

19 Low-Power (LP) HCSL output pairs with 85Ω Zout Features.
LP-HCSL outputs with 85Ω Zout; eliminate 76 resistors, save 130mm2 of area.
SMBus OE bits; software control of each output.
9 selectable SMBus addresses; multiple devices can share same SMBus segment.
Selectable PLL bandwidths; minimizes jitter peaking in cascaded PLL topologies.
Hardware/SMBus control of PLL bandwidth and bypass; change mode without power cycle.
Spread spectrum compatible; tracks sp.
