+3.3V Output Supply for external circuit (1.5A max). Do not
connect when external circuit has its own
power supply

Ground. All GND lines on the external circuit
should be connected to ensure proper shielding
between data lines
3 BCLK_IN Input Bit Clock input. TDM_IN* lines are sampled on
the rising edge of this signal

5 LRCLK_IN Input Left/Right Clock input (Wordclock).
Must be a 50% duty cycle.
First half of the TDM_IN* audio channels are
read during LRCLK_IN=0, second half of
TDM_IN* channels during LRCLK_IN=1
7 TDM_IN0 Input Audio data input line 0.
Must be 32 bit per channel, left-justified or I2S
depending on DIP setting. Only the first 24 bits
of each channel are read, the rest is ignored.
