CS4270
5.2.3 System Clocking
The CS4270 will operate at sampling frequencies from 4 kHz to 216 kHz. This range is divided into three
speed modes as shown in
Table 4
.
5.2.4 Clock Ratio Selection
In Control Port Master Mode, the user must configure the mode bits (M0, M1, M2) to set the speed mode
and select the appropriate clock ratios. Depending on whether the CS4270 is in Master or Slave Mode,
different MCLK/LRCK and SCLK/LRCK ratios may be used. These ratios as well as the Control Port Reg-
ister Bits are shown in
Table 5
,
Table 9
and
Section 8.3 on page 35
.
