Audio Data Capture Block

6.1.3
The ADV7511W supports multiple audio interfaces and formats: I2S, S/PDIF and HBR. The ADV7511W supports
audio input frequencies of 32kHz, 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz, and higher (with use of HBR).
The MCLK signal is optional unless specifically listed in
left-justified serial audio, right-justified serial audio and AES3 stream formats. The Audio Data Capture Block captures
the audio samples and converts them into audio packets which are sent through the HDMI link (if the ADV7511W is
set in HDMI mode). Please refer to the ADV7511 Programming Guide for more information.

Supported Audio Input Format and Implementation

6.1.3.1
ADV7511W is capable of receiving audio data for packetization and transmission over the HDMI interface in any of
the following formats:
■ Inter IC Sound (I2S)
■ Sony/Philips Digital Interface (S/PDIF)
■ High Bit-Rate (HBR)
