Serial Data Interface

(Related Pins) LRCK, BCK, SOUT, SIN, MASL, MLSL

The serial data format is common for both SIN (DA converter

input) and SOUT (AD converter output), consisting of two

channels per sampling serial data represented by 2’s com-

plement. Each channel is divided into 32-bit slots, of which

16 bits are handled as data.

MASL is used to select whether the 16 bits of valid data is

placed in the first or the second half of the 32-bit slots.
