NXP Semiconductors Linear - Linear - Video Processing - CBTL12131ET,518 CBTL12131ET,518

The CBTL12131ET,518 is a DisplayPort multiplexer designed for bidirectional video applications in all-in-one computer systems. It facilitates efficient path switching between multiple display modes, allowing video routing from two DisplayPort sources to either an integrated display or an external sink. The device features four main ports, each supporting high-speed differential lanes for DisplayPort Main Link channels, along with AUX and HPD signal lanes. This multiplexer supports DisplayPort v1.1a at data rates of up to 2.7 Gbit/s and includes a programmable equalizer for channel loss compensation, which can be configured for various gain-frequency curves. The equalizer also allows for pre-emphasis and differential swing level adjustments, all of which can be set using board-strapping techniques. The device is powered by a single 3.3V supply and has low current consumption, making it suitable for power-sensitive applications. Additional features include active management of HPD signals, link state detection, and the ability to configure the direction of signals based on the connected device type. The CBTL12131ET,518 is housed in a compact TFBGA64 package, making it a versatile choice for systems requiring high-performance video multiplexing.
