Initialization and Power-Down
The initialization and power-down sequence flow chart is shown in Figure 12. The CS4361 enters the pow-
er-down state upon initial power-up. The interpolation filters and delta-sigma modulators are reset, and the
internal voltage reference, multi-bit digital-to-analog converters, and switched-capacitor low-pass filters are
powered down. The device will remain in the Power-Down Mode until RST is released and MCLK and LRCK
are present. Once MCLK and LRCK are detected, MCLK occurrences are counted over one LRCK period
to determine the MCLK/LRCK frequency ratio. Power is then applied to the internal voltage reference. Final-
ly, power is applied to the D/A converters and switched-capacitor filters, and the analog outputs will ramp to
the quiescent voltage, VQ.
