Description
Reserved as 0. Always write 0 to this bit.
Force LOS to always OFF in regard to its effect on the output
signal. This forces the device into either the mute or “add
offset” state. The LOS bit in register 01h still reflects the
correct state of LOS.
0: LOS operates normally, muting or adding offset as
specified by the MUTE bit.
1: Muting or adding offset is always in place as specified by
the MUTE bit.
Force LOS to always ON in regard to its effect on the output
signal. This prevents the device from muting or adding
offset. The LOS bit in register 01h still reflects the correct
state of LOS.
0: LOS operates normally, muting or adding offset as
specified in the MUTE bit.
1: Muting or adding offset never occurs.
Configures LOS to be combined with the ENABLE
functionality.
0: Only the PD bit and ENABLE pin affect the power down
state of the output drivers.
1: If the ENABLE pin is set to ground, it powers down the
output drivers regardless of the state of LOS or the PD bit.
With the ENABLE pin set to V
the output drivers, and LOS=1 will leave the power down
state dependent on the PD bit.
Selects whether the device will MUTE when loss of signal
is detected or add an offset to prevent self oscillation. When
an input signal is detected (LOS=1), the device will operate
normally.
0: Loss of signal will force a small offset to prevent self
oscillation.
1: Loss of signal will force the channel to MUTE.
Sets the Termination Fault threshold for SDO, when SD is
set to SD rates (1). Combines with SDTFThreshLSB in
register 03h (default for combined value is 0101).

bits.
Compare command. Determines whether the peak value or
the current value of the Termination Fault counters is read
in registers 0Ah and 0Bh.
000: Resets compare value to 00; registers 0Ah and 0Bh
show current counter values. Sets detection to look for MAX
peak values.
001: Capture counter 0. Register 0Ah shows peak value.
010: Capture counter 1. Register 0Bh shows peak value.
011, 100: Reserved.
101: Resets compare value to 1Fh. Sets detection to look
for MIN peak values.
110, 111: Reserved.
Reserved as 00000. Always write 00000 to these bits.
