TIMING AND DATA FORMAT

The MS6323 accepts input serial data formats of 16-bit word length. Left and right data words are time

multiplexed. The MSB must always be first. The format of data input is shown in Figs. 2 and 3. With a HIGH level on

the word select input (WS), data is placed in the left input register and with LOW level on the WS input, data is placed

in the right register (Fig. 1). The data in the input registers are simultaneously latched in the output registers which

achieve the maximum dynamic range at the outputs of OP1 and OP2(Fig. 1). In this way the maximum dynamic range

is achieved over the entire power supply range.
