DESCRIPTION
The M02066 is a highly integrated, programmable laser driver intended for SONET/SDH applications with FEC to 3 Gbps. Using differential PECL data and clock inputs, the M02066 supplies the bias and modulation current required to drive an edge-emitting laser. The modulation output can be DC-coupled to the laser diode, giving a significant power saving over ACcoupled operation. The M02066 includes automatic power control to maintain a constant average laser output power over temperature and life. In addition, the modulation current can be 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.
High speed operation; suitable for applications to 3 Gbps. Typical rise/fall times of 90 ps. DC or AC coupled modulation drive. Differential data and clock inputs to minimize pattern dependent jitter. Independently Programmable Laser Bias and Modulation currents. Bias current to 100 mA and modulation current to 85 mA at VCC = 3.3 V Automatic Laser Power Control, with programmable temperature compensation and `Slow-Start'. Bias and modulation current monitor Operates with +3.3 Volt supply Functionally compatible with MAX 3869 The M02066-51 is available in die form or packaged (BCC+24 or TQFP32); the M02066-21 is available packaged in a BCC+24 or TQFP32.

FUNCTIONAL DESCRIPTION Overview
The M02066 laser driver consists of a high-speed modulation driver and a laser bias generator with mean power control (MPC). It is optimized for high speed, low power operation at 3.3V supply. To minimize the patterndependent jitter of the input signal, the device accepts an input clock signal for data retiming. This feature can be enabled using the external CEN pin. Fig. 4

Modulator
The M02066 modulation output is optimized for driving a 25 load; the minimum required voltage at OUT+ and OUT- is 0.6V. 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 = 39 , CSHUNT = 3.9 pF. These values will need to be optimized for a specific laser.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. See Fig. 3. The modulator output stage is designed to drive up to 85mA in either AC-coupled or DC-coupled mode. DC-coupled performance depends on the laser used. RMODSET determines the modulation current according to the following formula: IMOD = 350/RMODSET

M02066
3.3 Volt Laser Driver for Applications to 3 Gbps FUNCTIONAL DESCRIPTION Mean Power Control
To maintain constant average optical power, the M02066 incorporates a control loop to compensate for the changes in laser threshold current over temperature and lifetime. A monitor photodiode mounted in the laser package is used to convert the optical power into a photocurrent. The MPC loop adjusts the laser bias current so that the voltage at PD is matched to an on-chip reference voltage. The external resistor (RMPCSET) sets the optical power. RMPCSET = 1.28/IPIN IPIN is the mean current from the monitor photodiode at the required mean laser power level (see laser datasheet).The time constant of the loop is determined by CMPC. In some applications the internal capacitance at CMPC may be sufficient and an external CMPC will not be required. There are two safety features integrated into the MPC loop; an Over-Current Alarm and an MPC loop failure alarm. The Over-Current Alarm (OCA) circuit limits the maximum bias current generated by the M02060. 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. 5 shows the maximum bias current limit vs ROCA. Fig. 6

M02066
3.3 Volt Laser Driver for Applications to 3 Gbps FUNCTIONAL DESCRIPTION Safety Logic
Safety logic is provided in order to limit the maximum bias current. The bias current at which the safety logic trips is set by an external resistor to ground (ROCA) from the OCASET pin. When the bias current limit is reached alarm flag OCA is asserted LOW. A loop failure alarm is also provided to detect when the bias current can no longer be adjusted to achieve the desired average optical power.
Enable Control
Preliminary Information
The M02066 incorporates a dual laser driver enable function. When ENA is LOW or DIS is HIGH, both the bias and modulation currents are off. DIS and ENA are available on the M02066 die only, DIS is available on the BCC package only, ENA is available on the TQPF package.
Data Input Latch
To minimize input data pattern-dependent jitter, a differential clock signal can be connected to the data input latch. If CEN is HIGH, the input data is retimed by the rising edge of CLK+. If CEN is LOW, the input data is directly connected to the output stage. If CEN is left floating it will be pulled HIGH by the internal circuitry. When this latch function is not used, connect CLK+ to VCC and leave CLK- unconnected.
Current Monitors
The M02066 features bias and modulation current monitor outputs. The BIASMON output sinks a current equal to nominally 1/60 of the laser bias current (IBIAS). The MODMON output sinks a current equal to nominally 1/60 of the laser peak to peak 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-1.6V and a voltage at MODMON greater than VCC - 1.0V. These pins should be tied to VCC if not used.

M02066
3.3 Volt Laser Driver for Applications to 3 Gbps FUNCTIONAL DESCRIPTION Temperature Compensation
The reduction in slope efficiency of typical laser diodes caused by increased temperature can be compensated by utilising the TCSTART and TCSLOPE features of the M02066. Under closed loop conditions the average optical power will be maintained by the Mean Power Control loop, compensating for factors such as temperature and age. However, as the laser slope efficiency reduces with increasing temperature the laser diode will require a greater peak to peak current swing in order to maintain the same peak to peak optical output swing. To this end the M02066 senses temperature and can be programmed to increase the modulation current amplitude accordingly. Two external resistors are used to program the temperature compensation. The temperature (TCSTART) at which the compensation begins to take effect is set by a resistor (RTCSTART) from the TCSTART pin to ground. The rate of increase of modulation current with temperature (beyond TCSTART) is set by a resistor (RTCSLOPE) from the TCSLOPE pin to ground. As a safety feature, the M02066 limits the increased modulation current to twice the initial (ambient) modulation current. The effects of the two programming resistors are shown schematically in the Temperature Compensation graph below. If using the TQFP package; only TCSLOPE is programmable, TCSTART is connected to 0 V. For more details on temperature compensation see the appropriate applications note.
