Table 8. Soft Ramp and Zero Cross Enable
Soft Ramp and Zero Cross Enable
Soft Ramp and Zero Cross Enable dictates that signal level changes, either by attenuation changes
or muting, will occur in 1/8 dB steps and be implemented on a signal zero crossing. The 1/8 dB level
change will occur after a timeout period between 512 and 1024 sample periods (10.7 ms to 21.3 ms
at 48 kHz sample rate) if the signal does not encounter a zero crossing. The zero cross function is
independently monitored and implemented for each channel.

The CS43L41 implements the channel mixing functions of the ATAPI CD-ROM specification. Refer
to Table 9 and Figure 28 for additional information.
