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.
