Using differential PECL data inputs, the CX02067 supplies the bias and modulation current for driving an edge-emitting laser. The modulation output can be DCcoupled to the laser diode, giving a significant power saving over AC-coupled operation. Automatic Laser Power Control, with programmable Temperature Compensation and `Slow-Start'. Bias and modulation current monitors Operates with +3.3 Volt supply Small BCC+24 package The CX02067 includes automatic power control to maintain a constant average laser output power over temperature and life. In addition, the modulation current is temperature compensated to minimize variation in extinction ratio over temperature. Output flags indicate laser end of life as well as failure of the APC circuitry to maintain average output power.

It is optimized for high speed, low power operation at 3.3 V supply. Fig. 2 demonstrates the functionallity of the CX02067. Fig. 3 The modulator output stage is designed to drive up to 85 mA in either AC-coupled or DC-coupled mode. DC-coupled performance depends on the laser used. 120 100 80 The CX02067 modulation output is optimized for driving a 25 load; the minimum required voltage at OUT+ and OUT- is 0.6 V. To interface with the laser diode, a matching resistor (RD) is required for impedance matching. An RC shunt network is necessary to compensate for the laser diode parasitic inductance, thereby improving the optical eye. Typical values are RSHUNT = 51 , CSHUNT = 3.3 pF IMOD (mA) Any capacitive loading at the cathode of a laser diode will degrade the optical output performance. An inductor is used to isolate the BIAS pin from the laser cathode. 60 40 Fig. 3 shows the typical IMOD vs RMODSET characteristic. 20 0 0 4000 8000 12000 16000 20000 24000 28000 32000 RMODSET () Preliminary Information - REV_B Information provided in this Data Sheet is PRELIMINARY and is subject to change without notice.

The time constant of the MPC loop is determined by CMPC. 100 10000 20000 30000 40000 R O C A ( ) The MPC loop FAILure alarm (FAIL) is generated by the CX02067 when the MPC loop can no longer maintain the constant current set by RMPCSET. When the MPC loop failure alarm is triggered the FAIL pin is asserted LOW. Enable Control The CX02067 incorporates a dual polarity laser enable function with both enable (ENA) and disable (DIS) inputs. Under normal operating conditions the ENA will be HIGH while DIS is LOW. Should ENA go LOW (or DIS go HIGH) both the bias and modulation currents will be disabled. Wire OR-ing the OCA and FAIL pins externally and connecting them to the ENA pin will automatically disable the bias and modulation currents when a failure occurs. 80 60 40 Current Monitors 20 0 0 5000 10000 15000 20000 25000 30000 50 85 35000 R M PC SET -40 0 25 Symbols shown indicate C There are two safety features integrated into the MPC loop; an Over-Current Alarm and an MPC loop failure alarm. Preliminary Information - REV_B The CX02067 features bias and modulation current monitor outputs. The BIASMON output sinks a current equal to nominally 1/55 of the laser bias current (IBIAS). The MODMON output sinks a current equal to nominally 1/55 of the laser modulation current (IMOD). BIASMON and MODMON should be connected through a pull-up resistor to VCC. Choose a pull-up resistor value that ensures a voltage at BIASMON greater than VCC - 1.6 V and a voltage at MODMON greater than VCC - 1.0 V. These pins should be tied to VCC if not used. Information provided in this Data Sheet is PRELIMINARY and is subject to change without notice. MindspeedTM Technologies, Proprietary and Confidential Page 9 of 14 Preliminary Information The CX02067 employs a Mean Power Control (MPC) loop to maintain a constant optical output power from the laser across temperature, time and power supply variations. Laser diodes used for communication purposes come with integrated photo-diodes to monitor the output power and provide the feedback for the MPC loop. The MPC loop (or its integrated safety features) cannot be used without this feedback. The Over-Current Alarm (OCA) circuit limits the maximum bias current generated by the CX02067. The bias current limit is set by an external resistor to ground, ROCA. When this limit is exceeded the OCA pin is asserted LOW. Fig. 6 shows the maximum bias current limit vs ROCA.
