PIN NAME FUNCTION
25 BIAS Laser Bias Current Output
29 OUT+ Positive Mod ulation-Current Output. IMOD flows throug h this pad when input data is high.
30 OUT- Negative Modulation-Current Output. IMOD flows through this pad when input data is low.
35 MD Monitor Diode Input. Connect this pad to a monitor photodiode anode. A capacitor to ground is required to filter high-speed AC monitor photocurrent.
34, 36, 40 GND3 Ground for APC
37 Vcc3 Power Supply for APC
38 CAPC A capacitor connected from this pad to ground controls the dominant pole of the APC feed- back loop. (CAPC = O.lpF)
44 APCSET A resistor connected from this pad to ground sets the desired average optical power. Connect 100kl from this pad to ground if APC is not used.
46 MODSET A resistor connected from this pad to ground sets the desired modulation current.
47 BIASMAX A resistor connected from this pad to ground sets the maximum bias current. The APC function can subtract from this maximum value, but can not add to it.
48 Vcc2 Power Supply for internal reference
