TDA19977BHV Triple input HDMI 1.4a compliant receiver interface with equalizer (up to 1080p for HDTV, and UXGA for PC formats)

The TDA19977A; TDA19977B is a three input HDMI 1.4a compliant receiver with embedded EDID memory. The built-in auto-adaptive equalizer, improves signal quality and allows the use of cable lengths of up to 25 m which are laboratory tested with a 0.5 mm (24 AWG) cable at 2.05 gigasamples per second. The HDCP (TDA19977A only) key set is stored in non-volatile OTP (One Time Programmable) memory for maximum security. In addition, the TDA19977A; TDA19977B is delivered with software drivers to ease configuration and use.

The TDA19977A; TDA19977B supports:

The TDA19977A; TDA19977B includes:

The TDA19977A; TDA19977B converts HDMI streams with or without HDCP (TDA19977A only) into RGB or YCbCr digital signals. The YCbCr digital output signal can be 4:4:4 or 4:2:2 semi-planar format based on the ITU-R BT.601 standard or 4:2:2 based on the ITU-R BT.656 format. The device can adjust the output timing of the video port by altering the values of tsu(Q) and th(Q). In addition, all settings are controllable using the I²C-bus
