Data Format
A “HIGH” on pin 14 (FORMAT) sets the input format to
I
2
S, and a “LOW” sets the format to Normal (MSB-first,
right-justified Sony format).
Soft Mute
A “LOW” on pin 18 (MUTE) causes both outputs to be
muted. This muting is done in the digital domain so there is
no audible “click” when the soft mute is enacted.
De-Emphasis
PCM1718 allows for digital de-emphasis for all three stan-
dard sampling frequencies:
