YDA136
■DAC Function
YDA136 has a 24-bit×2ch of DAC.
The DAC supports the following eight kinds of sampling frequencies (Fs), and it has an over sampling filter corresponding
to each sampling frequencies.
32kHz、44.1kHz、48kHz、64kHz、88.4kHz、96kHz、176.4kHz、192kHz
The output full-scale of this DAC is 1Vrms.
●DAC Interface
Be sure to input a digital audio signal from the following three terminals, SDIN, LRCLK, and SCLK.
DAC interface of YDA136 supports the seven DAC input formats.
Be sure to set up control registers, MOD2, MOD1, and MOD0, and then select a DAC input format to use.
When using the YDA136 as Digital Audio Signal mode, be sure not to stop a SCLK signal except when electronic volume
is mute, protection reset mode, or hard mute mode.

LRCLK
Left channel
Right channel
A SDIN bit is sampled by the rising edge of SCLK.
When LRCLK is “H”, be sure to input data for Left channel by right justified.
When LRCLK is “L”, be sure to input data for Right channel by right justified.
SDIN data is written into a DAC data register by the rising edge of LRCLK.
64-clock for one-word.

A SDIN bit is sampled by the rising edge of SCLK.
When LRCLK is “L”, be sure to input data for Left channel in left justified with a vacant bit.
When LRCLK is “H”, be sure to input data for Right channel in left justified with a vacant bit.
SDIN data is written into a DAC data register by the falling edge of LRCLK.
