Input pin for AKM test. Connect it to DVSS for Normal operation.

Input pin for AKM test. Connect it to DVSS for Normal operation.
Power supply for Digital circuit.
Ground for Digital circuit.
Alarms such as Optical output decline (OPTALM), Excessive LD
current (CURRALM), Exceptional temperature (TEMPALM) and
Irregular external signals (EXTALM1 and EXTALM2) can be
selected by EEPROM / Register setting as target alarms available on
TXFAULT-pin output.
When any of the selected alarms (ALM) is detected, TXFAULT-pin
becomes ”High-Z“ output, and it becomes “H“ level with a pulled-up
resistor connection. This pin is open-drain type and should be
connected to DVDD via a 4.7k ~ 10k
Ω
resistor.
With RE_SFP_SET
＝
“0“ (SFP support mode setting), TXFAULT-
pin output is held at “H“ level when any of the selected alarms is
detected till the shutdown request is released by “H“ to “L“ transition
on TXDIS-pin.
Serial data input / output pin for Digital interface.
This pin is open-drain type and should be connected to DVDD via a
4.7k ~ 10k
Ω
resistor.

BURST
Burst signal input. It is active during “H“ input period (valid data
period). When this pin is not used, connect it to DVSS.
When this pin is at “H“ input, Bias current DAC (I-DAC2) output
and Modulation current DAC (I-DAC1 or V-DAC3) output are
disabled. Refer to Table 7-1 and Table 7-2.
At RE_SFP_SET
＝
“0“ (SFP support mode setting), a logical sum of
TXFAULT output and TXDIS-pin input become a disable request.
At RE_SFP_SET
＝
“1“, TXDIS-pin input becomes a disable request.
When this pin is externally pulled-up, use a higher than 4.7k
Ω
resistor. When this pin is not used, connect it to DVSS.
Power supply for Analog circuit.
Ground for Analog circuit.
Monitoring PD (Photo Diode) voltage input.
The detected monitor PD current is I to V converted by external
resistor and capacitor. Please adjust the cut-off frequency of an LPF
to be within 5k ~ 10kHz which is composed of external resistor (Rpd)
and capacitor (Cpd).
When this pin is not used, it is recommended to connect it to AVSS.
Bias current monitor. A current multiplied by 0.012 [Typ.] of the
I-DAC2 output current is sourced from this pin. When to convert the
current to a voltage by an external resistor, select the resistor value
such that BIASMON-pin voltage
≦
1.3 V.
Ground for I-DAC2.
