To operate the CS4271 with an externally generated MCLK signal, no crystal should be used, XTI should be con-
nected to ground and XTO should be left unconnected. In this configuration, MCLK is an input and must be driven
externally with an appropriate speed clock.
5.2.3.2
Clock Ratio Selection
Depending on the use of an external crystal, or whether the CS4271 is in Master or Slave Mode, different
MCKL/LRCK and SCLK/LRCK ratios may be used. These ratios as well as the Control Port Register Bits that must
be set in order to obtain them are shown in Tables 8 and 9 below.
Notes: 25. For the Ratio1 and Ratio0 bits listed above, “d” indicates that any value may written.
