PI3DBS16222

3.3V 20Gbps 4 Channel 2x2 Exchange Switch

Description

The PI3DBS16222 is a differential exchange switch featuring pass-through pinout. It supports 2x2 exchange switch operating at 20Gbps, enables applications in PCI Express Gen 4, USB 3.1 Gen 2, Thunderbolt 3, 10G BASE-KR.


With the select control input low, Port A connects to port B, and port C connects to port D for an 8-channel differential pass-though. When the select control input is high Port A connects to port D, and port B connects to port C.
