Description

The 9DBL02x3/9DBL04x3/ 9DBL06x3/9DBL08x3 buffers are

low-power, high-performance members of Renesas' full featured

PCIe family. The buffers support PCIe Gen1–5 and provide a Loss

of Signal (LOS) indicator.

PCIe Clocking Architectures

▪ Common Clocked (CC)

▪ Independent Reference (IR) with/without SSC (SRIS, SRNS)

Typical Applications

▪ PCIe Riser Cards

▪ nVME Storage

▪ Networking

▪ Accelerators

▪ Industrial Control/Embedded

Key Specifications

▪ Additive PCIe Gen5 CC jitter < 60fs RMS (fanout mode)

▪ PCIe Gen5 CC jitter < 150fs RMS (High-BW ZDB Mode)

Features

▪ LOS open-drain output indicates loss of input clock

▪ 2 to 8 Low-Power HCSL (LP-HCSL) outputs eliminate 4

resistors per output pair

▪ 9DBLxx4x devices provide integrated 100Ω terminations

▪ 9DBLxx5x devices provide integrated 85Ω terminations

▪ See AN-891 for easy coupling to other logic families

▪ Spread-spectrum compatible

▪ Dedicated OE# pin for each output

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

▪ 3 selectable SMBus addresses

▪ Extensive SMBus-selectable features allow optimization to

customer requirements

▪ SMBus interface not required for device operation

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

▪ Space-saving 4 × 4 mm 24-VFQFPN to 6 × 6 mm 48-VFQFPN

packages (see Ordering Information table for details)
