Description

Pericom Semiconductor’s PI3VDP12412 mux/demux is targeted

for next generation digital video signals. This device can be used

to connect a DisplayPort™ Source to two Independent Display-

Port Sinks or to connect two DisplayPort sources to a single DP

display.

PI3VDP12412 supports DisplayPort 1.2 which requires a data

rate of 5.4 Gbps. PI3VDP12412 offers excellent signal integrity at

this high data rate with very low insertion loss, good return loss,

and very small crosstalk.

PI3VDP12412 is available in two package types, a 5 mm x 5 mm

48 BGA and a 3.5 mm x 9 mm 42 TQFN. The BGA consumes less

board space. The TQFN achieves slightly better signal integrity.

Application

Routing of DisplayPort signals with low signal attenuation be-

tween source and sink.
