9DBL02x2/9DBL04x2/9DBL06x1/9DBL08x1C

2 to 8-Output 3.3V PCIe Zero-Delay/Fanout Buffers

The 9DBL02x2/9DBL04x2/9DBL06x1/9DBL08x1C

Features

▪ 2 to 8 Low-Power HCSL (LP-HCSL) outputs

buffers are low-power, high-performance members of

Renesas' full featured PCIe family. The buffers

support PCIe Gen1 through Gen5.

eliminate 4 resistors per output pair

▪ 9DBLxx4x devices provide integrated 100Ω

terminations

PCIe Clocking Architectures

▪ Common Clocked (CC)

▪ 9DBLxx5x devices provide integrated 85Ω

terminations

▪ Independent Reference (IR) with and without

spread spectrum (SRIS, SRNS)

▪ See AN-891 for easy coupling to other logic

families

▪ Spread-spectrum compatible

Typical Applications

▪ PCIe Riser Cards

▪ nVME Storage

▪ Dedicated OE# pin for each output

▪ 1MHz to 200MHz operation in fan-out mode

▪ 3 selectable SMBus addresses

▪ Networking

▪ Extensive SMBus-selectable features allow

optimization to customer requirements

▪ Accelerators

▪ Industrial Control/Embedded

▪ SMBus interface not required for device operation

▪ -40°C to +85°C operating temperature range

▪ Space-saving packages:
