Pin Descriptions (BCC+24)

Pin No.

Name

Function

1

CEN

Clock enable input (TTL/CMOS). Set HIGH or not connected to use CLK inputs, LOW when not using CLK inputs

2

DIS

Bias and modulation output disable (TTL/CMOS). LOW for normal operation

3

GND

Ground

4

MON

5

FAIL

Mean power control failure indicator (TTL/CMOS). Goes LOW when control loop is no longer able to maintain constant

current at PD

6

OCA

Power supply

8

BIAS

Laser bias current output

Power supply

10

OUT+

11

OUT-

12

Ground for output stage. (inductor to ground)

13

PD

Monitor photo diode input. This input is connected to the monitor photodiode anode for automatic power control. A

resistor between this pin and ground sets the mean optical power

14

Mean power control loop dominant pole capacitor

Modulation current set. Connect a resistor between this pin and ground to set

19

Over current alarm set. Connect a resistor between this pin and ground to set

20

Power supply

21

Positive data input (PECL). Self biased
