Table 1. Input video formats supported by the CAT6613
Notes:
1. Table cells that are left blanks are those format combinations that are not supported by the CAT6613.
2. Input channel number is defined by the way the three color components (either R, G & B or Y, Cb & Cr) are
arranged. Refer to Video Data Bus Mappings for better understanding.
3. Embedded sync signals are defined by CCIR-656 standard, using SAV/EAV sequences of FF, 00, 00, XY.
Audio Data Capture and Processing
The CAT6613 supports all audio formats and interfaces specified by the HDMI Specification v1.3
through I2S, S/PDIF and optional one-bit audio inputs.
I2S
Four I2S inputs are provided to support 8-channel uncompressed audio data at up to 192kHz sample
rate. If the input audio data come with a multiple (master) clock, pin 5 (MCLK) takes in the clock to
faciliate audio processing. Note that this is optional. By default CAT6613 generates the MCLK
internally to process the audio. Neither I2S nor S/PDIF inputs requires MCLK input, coherent or not.
However, if the user prefers inputing MCLK from external audio source, such configuration could be
enabled through register setting. Refer to CAT6613 Programming Guide for such setting. The
supported multiplied factor and sample frequency as well as the resultant MCLK frequencies are
summarized in Table 2.
S/PDIF
The S/PDIF input supports 2-channel uncompressed PCM data (IEC 60958) or compressed
multi-channel data (IEC 61937) at up to 192kHz. By default the clock of S/PDIF is carried within the
datastream itself via coding. The CAT6613 could also process the S/PDIF audio with coherent MCLK
input as indicated in Table 2.
