6.3.6

Mutec Pin Control (MUTEC)

Default = 0

0 - Two Mute control signals

1 - Single mute control signal on MUTEC1

Function:

Selects how the internal mute signals are routed to the MUTEC1 and MUTEC234 pins. When set to ‘0’,

a logical AND of DAC pair 1 mute control signals are output on MUTEC1 and a logical AND of the mute

control signals of DAC pairs 2, 3, and 4 are output on MUTEC234. When set to ‘1’, a logical AND of all

DAC pair mute control signals is output on the MUTEC1 pin, MUTEC234 will remain static. For more in-

formation on the use of the mute control function see the MUTEC1 and MUTEC234 pins in Section 5.

Filter Control (Address 04h)

6.4.1

Interpolation Filter Select (FILT_SEL)

Default = 0

0 - Fast roll-off

1 - Slow roll-off

Function:

This function allows the user to select whether the interpolation filter has a fast or slow roll off. For filter

characteristics, please see Section 2.

6.4.2

De-Emphasis Control (DEM)

Default = 00

00 - Disabled

01 - 44.1 kHz

10 - 48 kHz

11 - 32 kHz

Function:

Selects the appropriate digital filter to maintain the standard 15

s/50 s digital de-emphasis filter re-

sponse at 32, 44.1 or 48 kHz sample rates. (see Figure 13)

De-emphasis is only available in Single-Speed Mode.

6.4.3

Soft Ramp-Down Before Filter Mode Change (RMP_DN)

Default = 0

0 - Disabled

1 - Enabled

Function:

If either the FILT_SEL or DEM bits are changed, the DAC will stop conversion for a period of time to

change filter values. This bit selects how the data is effected prior to and after the change of the filter val-

ues. When this bit is enabled, the DAC will ramp down the volume prior to a filter-mode change and ramp
