16. APPENDIX J: SWITCH SUMMARY
Table 18 lists the jumper settings required for all
four host interface modes of the CS492x/CS493xx.
Table 19 shows all of the digital output formats that
can be selected for the CS5334 with switch S4.
Please see the CS5334 datasheet for a more de-
tailed description of available digital output for-
mats.
Table 20 shows all of the digital input formats that
can be selected for the CS4340 with S4. Please see
the CS4340 datasheet for a more detailed descrip-
tion of available digital input formats.
Table 21 shows all of the digital output formats that
can be selected for the CS8414 with switch S1.
Please see the CS8414 datasheet for a more de-
tailed description of available audio serial port for-
mats.
Table 23 shows all of the digital input formats that
can be selected for the CS8404A with switch S2.
Please see the CS8404A datasheet for a more de-
tailed description of available digital input format.
Table 22. shows all available PLL settings for the
external PLL on the CDB4923/4930.
Table 24 lists all possible data routing possibilities
and the associated MCLK source for the
CDB4923/300.
