GENERAL DESCRIPTION
Aside from the various video output formats supported, the IT6613 also encodes and transmits up to 8 channels of I2S digital audio, with sampling rate up to 192kHz and sample size up to 24 bits. In addition, an S/PDIF input port takes in compressed audio of up to 192kHz frame rate, while Super Audio Compact Disc (SACD) is supported through dedicated DSD ports (Direct Stream Digital ports) at up to 88.2kHz one-bit audio. The High-Bit Rate (HBR) audio is also provided by the IT6613 in two interfaces: with the four I2S input ports or the S/PDIF input port. With both interfaces the highest possible HBR frame rate is supported at up to 768kHz. Each IT6613 chip comes preprogrammed with an unique HDCP key, in compliance with the HDCP 1.4 standard so as to provide secure transmission of high-definition content. Users of the IT6613 need not purchase any HDCP keys or ROMs. The IT6613 is pin compatible with the CAT6613, the previous generation HDMI 1.3 transmitter. FEATURES
