3.4
To accommodate the increasingly complex requirements of digital audio systems, the CS4392 incorpo-
rates selectable interpolation filters for each mode of operation. A fast and a slow roll-off filter is available
in each of Single, Double, and Quad Speed modes. These filters have been designed to accommodate a
variety of musical tastes and styles. Bit 5 of the Mode Control 3 register (06h) is used to select which filter
is used. Filter specifications can be found in Section 8, and filter response plots can be found in Figures 12
to 35.
In stand-alone mode, only the fast roll-off filter is available.
3.5
The required MCLK to LRCK and suggested SCLK to LRCK ratios are outlined in table 1. MCLK can be
at any phase in regards to LRCK and SCLK. SCLK, LRCK and SDATA must meet the phase and timing
relationships outlined in Section 7. Some common MCLK frequencies have been outlined in tables 2 to 4.
*Note:These clocking ratios are only available in Control Port Mode when the MCLK Divide bit is enabled.
