Descriptions
The IT6601 is an HEAC transmitter and receiver with CEC function, fully compliant with HDMI1.4. The IT6601 supports 100Base-TX IEEE802.3 Ethernet standard, IEC60958-1 audio standard and HDMI1.4 CEC feature.
HDMI Ethernet and Audio Return Channel (HEAC) use signal pair composed of the HEAC- and HEAC+ lines or use only the HEAC+ line for ARC function. The HEAC transmitter is composed HEC transmitter and ARC transmitter. HEC transmitter employs MLT-3 signaling in differential mode. ARC transmitter employs a single SPDIF signal in common mode or signal mode. All combinations of HEC and ARC are allowed.
The IT6601 integrates a fully-compliant CEC PHY, which when operating with an external MCU provides full CEC supports. CEC controller handles arbitration, flow control, frame re-transmission, frame validation error detection and error handling.
