Figure 2–4. DSP Compatible Serial Interface Format (for 16-bits)
Note the following characteristics of this protocol.
MCLK = 256 Fs only
SCLK = 64 times the sampling frequency.
Serial data is sampled with the falling edge of SCLK.
Serial data is transmitted on the rising edge of SCLK.
2.15 Sampling Frequency Ranges
The TLC320AD77C supports two sampling frequency ranges.
When in the normal option ranging from 16 kHz up to 48 kHz, SPDMOD = low is used.
When in the fast option ranging from greater than 48 kHz up to 96 kHz, SPDMOD = high is used.
NOTE:
The high speed clocks should never be applied while SPDMOD is low in order to
avoid glitches in the DAC and ADC outputs.

Initial Power Up
For initial power up, the ADC and DAC outputs are valid after the 150 ms settling time required for the analog
stages. Holding the power down pin low while ramping up the power supplies is recommended to avoid
glitches in the DAC output.
