描述 Description

The 9DMV0131B/9DMV0141B are 1.8V members of IDT’s

full-featured PCIe clock family. The 9DMV0131B uses external

series resistors for maximum flexibility, while the 9DMV0141B

integrates output terminations for direct connection to 100Ω

transmission lines. An OE# pin provides optimal system control

and power management. The parts provide asynchronous or

glitch-free switching modes.

特性 Features

? Direct connection to 100Ω loads saves 4 resistors

(9DMV0141B)

? External series resistors allow use in 85Ω or 100Ω systems

(9DMV0131B)

? 1.8V operation; 12mW typical power consumption

? Selectable asynchronous or glitch-free switching; allows the

mux to be selected at power up even if both inputs are not

running, then transition to glitch-free switching mode

? OE# pin for flexible power sequencing

? HCSL differential inputs

? Spread spectrum tolerant; allows reduction of EMI

? 1MHz to 200MHz operating frequency

? Configuration accomplished with strapping pins, no SMBus

needed

? Space-saving 3 × 3 mm 16-VFQFPN; minimal board space
