TDA9989
HDMI 1.3a transmitter with CEC support
The I2S-bus input interface can receive up to 24-bit wide audio samples via the serial data
input with a clock frequency of at least 32 times the input sample frequency fs.
Audio samples with a precision better than 24-bit are truncated to 24-bit. If the input clock
has a frequency of 32fs, only 16-bit audio-samples can be received. In this case, the 8
LSBs will be set to 0. If the input clock has a frequency of 64fs and is left justied or
Philips, the audio word is truncated to 24-bit format and other bits padded with zeros. If
the input clock has a frequency of 64fs and is right justied, audio sample must be strictly
24-bit length.
The serial data signal carries the serial baseband audio data, sample by sample left/right
interleaved.
The word select signal indicates whether left or right channel information is transferred
over the serial data line.
a. Philips format.
b. Left justied format.
c. Right justied format.
