Product Description

The 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.
