CBTL06122 Datasheet | NXP Semiconductors

Rev. 02 - 16 April 2009 .. High-performance Display Port/PCIe Gen2 hex display multiplexer Product data sheet 1. General description The CBTL06122 is a six-channel (‘hex’) multiplexer for Display Port and PCI Express Gen2 applications. It provides four differential channels capable of switching or multiplexing (bidirectional and AC-coupled) PCI Express Gen2 or Display Port signals, using high-bandwidth pass-gate technology. Additionally, it provides for switching/multiplexing of the Hot Plug Detect signal as well as the AUX or DDC (Direct Display Control) signals, for a total of six channels. The CBTL06122 is designed for high-performance PCI Express Gen2 and Display Port applications. The device is available in two different pinouts (A and B, orderable as separate part numbers) to suit different motherboard layout requirements. The typical application of CBTL06122 is on motherboards, docking stations or add-in cards where the graphics and I/O system controller chip utilizes I/O pins that are configurable for either PCI Express or Display Port operation. The hex display MUX can be used in such applications to route the signal from the controller chip to either a physical Display Port connector or a PCI Express connector using its 1 : 2 multiplexer topology. The controller chip selects which path to use by setting a select signal (which can be latched) HIGH or LOW. Optionally, the hex MUX device can be used in conjunction with an HDMI/DVI level shifter device (PTN3300A, PTN3300B or PTN3301) to allow for Display Port as well as HDMI/DVI connectivity.
