5 to 9-Output 1.8V Low-Power Buffers for PCIe Gen1–5 9DBV05x1/9DBV07x1/ 9DBV09x1 Datasheet Description The 9DBV05x1/9DBV07x1/9DBV09x1 fanout buffers are low-power, high-performance fanout buffers in Renesas' Full Featured PCIe family. The buffers have 5, 7 or 9 outputs with each output having an OE# to support the PCIe CLKREQ# function. The devices have 3 selectable SMBus addresses. PCIe Clocking Architectures ▪ Common Clocked (CC) ▪ Independent Reference (IR) with and without spread spectrum (SRIS, SRNS) Typical Applications ▪ Servers/High-performance Computing ▪ nVME Storage ▪ Networking ▪ Accelerators ▪ Industrial Control Key Specifications ▪ PCIe Gen5 CC additive phase jitter <40fs RMS ▪ 12kHz–20MHz additive phase jitter = 165fs RMS at 156.25MHz (typical) ▪ Output-to-output skew < 50ps ▪ Power consumption as low as 41mW (typical) ▪ 1MHz to 200MHz operating frequency Features ▪ 5–9 Low-Power HCSL (LP-HCSL) outputs 100Ω outputs eliminate 4 resistors per output pair (9DBVxx41) 33Ω outputs eliminate 2 resistors per output pair allowing use in both 85Ω and 100Ω systems (9DBVxx31) ▪ Easy AC-coupling to other logic families, see application note AN-891 ▪ Spread spectrum compatible ▪ OE# pins support PCIe CLKREQ# function ▪ 3 selectable SMBus addresses ▪ 3.3V tolerant SMBus interface ▪ SMBus-selectable features allow optimization to customer requirements: Individual slew rate control for each output Differential output amplitude Device contains default configuration;...
