Transceiver supports HDMI and DisplayPort

The TXC-44143 dual mode transceiver supports five full HDMI Ethernet and Audio-return Channels (HEAC) with a 10/100-Mbit Ethernet PHY and analog switches. The IC can be used for digital TV, A/V receiver, home theater, and A/V converter/switch box applications.

The 324-ball RoHS BGA packaged chip has two LVTTL parallel I/O ports and supports HDMI v1.4a with TMDS speed up to 3.0 Gbits/s and DisplayPort v1.1a with link speed at 1.62/2.70 Gbits/s. The IC’s HDP function is a dual-mode PHY, which supports both HDMI and DisplayPort without needing a switch. HDP’s auto-detect capability facilitates connectivity between PCs and HDMI consumer devices with significantly simplified software control and bill of materials.
