Description
Pericom Semiconductor's PI3TB212 is a high-speed multi-
plexer/demultiplexer switch. PI3TB212 can switch signals up
to 10.3125Gbps for DisplayPort and Thunderbolt™(TB) ap-
plications. The device supports 5.4Gbps for DisplayPort and
10.3125Gbps for Thunderbolt.
PI3TB212 is a major advance over first-generation Thunderbolt
solutions. PI3TB212 integrates the 10.3125 Gbps Thunderbolt
path. This eliminates external PIN diode switches, thereby
reducing board space, reducing cost, and improving link perfor-
mance.
PI3TB212 achieves excellent signal integrity at 10.3125 Gbps as
evidenced by measured results.
