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
