Gen1 hex display multiplexer

The CBTL06121 is a six-channel multiplexer designed for Gen1 speeds, at 2.5 Gbit/s for PCI Express or 2.7 Gbit/s for DisplayPort. It provides four differential channels capable of switching or multiplexing (bidirectional and AC-coupled) PCI Express or DisplayPort signals.

CBTL06121 is typically used on motherboards, docking stations or add-in cards where the graphics and I/O system controller chip utilizes I/O pins.The hex display MUX can be used to route the signal from the controller chip, which selects the path to be used by setting a select signal (which can be latched) HIGH or LOW.
