IT6623_2:1 HDMI 1.4a 3D Transceiver with Audio I/O
The IT6623 is HDMI 1.4a transceiver with a dual-port HDMI 1.4a receiver and a single-port HDMI1.4a Transmitter, can extract audio signals out to external audio processor and then feed the processed audio signals into IT6623 to renew audio bit stream which combine with video bit stream as the new AV bit stream, then output to HDMI Sink via the IT6623 transmitter.
