4.7.6.1 Output Mute Control Mode

Each of the outputs on the GS12341 have independent mute control modes, which can

be configured through the host interface.

The following are the four output mute control modes:

1. The outputs automatically mute on LOS (default).

2. The outputs automatically mute on LOS and during rate search.

3. The outputs never mute.

4. The outputs are always muted.

The first mute control mode is the default power-up configuration for both output

drivers (the CTRL_OUTPUT<n>_AUTO_MUTE control parameter in register 0x49 is set

to 1b). In this mode, the outputs will automatically mute on the assertion of LOS. This

includes LOS as a result of setting up Squelch Adjust (see Section 4.2.1 for more details).

In addition to mute on LOS, with auto mute control mode configured, setting the

CTRL_OUTPUT<n>_AUTO_MUTE_DURING_RATE_SEARCH control parameter in

and begins to rate search.

The outputs can be manually configured to never mute by setting both the

CTRL_OUTPUT<n>_AUTO_MUTE and CTRL_OUTPUT<n>_MANUAL_MUTE control

parameters in register 0x49 to 0b. Alternatively, the outputs can be manually configured

to always be muted by setting the CTRL_OUTPUT<n>_AUTO_MUTE and

CTRL_OUTPUT<n>_ MANUAL_MUTE control parameters to 0b and 1b respectively.

4.7.6.2 Output Disable Control Mode

Each of the outputs on the GS12341 also have independent disable control modes,

which can be configured through the host interface.

The following are the three output disable control modes:

1. The outputs are never disabled (default).

2. The outputs are automatically disabled on LOS.

3. The outputs are always disabled.

The first disable control mode is the default power-up configuration for both output

drivers (the CTRL_OUTPUT<n>_AUTO_DISABLE and

CTRL_OUTPUT<n>_MANUAL_DISABLE control parameters in register 0x4A are both

set to 0b). In this mode, the outputs will never disable. By setting the

CTRL_OUTPUT<n>_AUTO_DISABLE control parameter in register 0x4A to 1b, the

outputs will automatically disable on the assertion of LOS. This includes LOS as a result

of setting up Squelch Adjust (see Section 4.2.1 for more details).

The output can be manually disabled by leaving the

CTRL_OUTPUT<n>_AUTO_DISABLE control parameter set to 0b and setting the

CTRL_OUTPUT<n>_MANUAL_DISABLE control parameter to 1b.

The disable control mode takes precedence over the output mute control mode.
