10 / 40 page CS4392 10 DS459PP3 3.4 Interpolation Filter 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 System Clocking 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. MCLK/LRCK SCLK/LRCK LRCK Single Speed 256, 384, 512, 768, 1024* 32, 48, 64, 96, 128 Fs Double Speed 128, 192, 256, 384, 512* 32, 48, 64 Fs Quad Speed 64 32 (16 bits only) Fs 96 32, 48 Fs 128, 256* 32, 64 Fs 192 32, 48, 64, 96 Fs Table 1.
