PCM1721’s internal PLL can be programmed for nine
different sampling frequencies (LRCIN), as shown in Table
I. The internal sampling clocks generated by the various
programmed frequencies are shown in Table II. Because of
finite limitations in the PLL’s M and N counters, errors
associated with specific frequencies are shown.

SPECIAL FUNCTIONS
PCM1721 includes several special functions, including digi-
tal attenuation, digital de-emphasis, soft mute, data format
selection and input word resolution. These functions are
controlled using a three-wire interface. MD (pin 8) is used
for the program data, MC (pin 7) is used to clock in the
program data, and ML (pin 6) is used to latch in the program
data. Table III lists the selectable special functions.
