Appendix C: Setting CLKIN/SCLK Ratio for Desired Sample Rate
In Slave sub-modes, the CS4218 detects the ratio between the CLKIN and SCLK rates and sets the
internal sample rate accordingly. The following formula can be used to determine the ratio of CLKIN
to SCLK for any desired sample rate for both Serial Modes 3 and 4, Slave sub-modes.
CLKIN
SCLK
=
(
256
×
Fsmax
)
(
BPF
×
Fs
)
where:
CLKIN =Master clock input
In SM3 Multiplier Slave sub-mode, CLKIN is replaced by 16* CLKIN.
SCLK
=Serial port bit clock.
Fsmax
=Maximum system sample rate.
Fs
=Desired sample rate.
BPF
=The number of bits per frame (256, 128, 64 or 32)
Example 1
: SM3-S, Fsmax = 48 kHz, Fs = 8 kHz, BPF = 64
CLKIN
SCLK
=
(
256
×
48000
)
(
64
×
8000
)
512
kHz
= 12.288

Example 2
: SM4-S, Fsmax = 8 kHz, Fs = 8 kHz, BPF = 32
CLKIN
SCLK
=
(

)
(

)
= 2.048
