Fault state* occurs
Fault state* occurs
PORDLY
Does not affect laser power
Fault state* occurs if V

LV
Does not affect laser power
If
POL
is a TTL LOW, a fault state* occurs; other-
wise, the circuit is in normal operation

If
POL
is a TTL HIGH, a fault state* occurs; other-

In common cathode without photodiode configura-
tion, a fault state* occurs; otherwise, does not affect
laser power
Fault state* occurs
If POL is a TTL LOW, a fault state* occurs; other-

Does not affect laser power. If optional FET is used,
the laser output is shut off.
FLTDLY
Any fault that occurs cannot be reset. Does not
affect laser power.

MODSET
Does not affect laser power
In common-anode configurations, the laser bias
current is shut off. In common cathode, high laser
power triggers a fault state.* Shutdown occurs if a
shutdown FET (M1) is used (Figures 9, 10).
BIASDRV
In common-cathode configurations, the laser bias
current is shut off. In common anode, high laser
power triggers a fault state.* Shutdown occurs if a
shutdown FET (M1) is used. If shutdown FET is not
used, other means must be used to prevent high
laser power.
Fault state* occurs
TC
Does not affect laser power
Table 5. Circuit Response to Various Single-Point Faults
*
A fault state asserts the FAULT pins, disables the modulator outputs, disables the bias output, and asserts the SHDNDRV pin.
