Description

The 9DML2855 is a 2-input, 8-output clock multiplexer supporting

PCIe Gen5 and DB2000Q applications. It supports today's

complex system power sequencing requirements with Power

Down Tolerant and Flexible Power Sequencing features. An OE#

pin for each output supports PCIe CLKREQ# functionality

Features

▪ Flexible Power Sequencing (FPS) ensures good behavior

when powered up without input clock

▪ Power-Down Tolerant Input (PDT) inputs: SEL_A_B#,

SADR0_tri, OE# pins

▪ Integrated terminations eliminate 32 resistors, saving 62mm2

of area

▪ 8 OE# pins; hardware control of each output. SMBus control

also available

▪ 3 selectable SMBus addresses

▪ Spread spectrum compatible; tracks spreading input clock for

EMI reduction

▪ Maximum operating frequency of 400MHz

▪ 6 × 6 mm 48-VFQFPN package
