1
VL (Input) - Digital interface power supply. Typically 1.8 to 3.3 VDC.
2
MCLK (Input) - The master clock frequency must be either 256x, 384x,
512x, 768x or 1024x the input sample rate in Base Rate Mode (BRM) and
128x, 192x, 256x, 384x the input sample rate in High Rate Mode (HRM).
Table 16 illustrates several standard audio sample rates and the required
master clock frequencies.
3
SCLK (Input/Output) - Clocks the individual bits of the serial data out of the
SDOUT pin. The required relationship between the Left/Right clock, serial
clock and serial data is defined by the DIF2-0 bytes when in Control Port
mode or by the DIF1-0 pins when in Stand-Alone mode.
4
SDOUT (Output) - Two’s complement MSB-first serial data is output on this
pin. The data is clocked out of SDOUT via the serial clock and the channel is
determined by the Left/Right clock. The required relationship between the
Left/Right clock, serial clock and serial data is defined by the DIF2-0 bytes
when in Control Port mode or by the DIF pin when in Stand-Alone mode.
5
VA (Input) - Analog power supply. Typically 1.8 to 3.3 VDC.
6
GND (Input) - Ground Reference.
