functional description 02066-DSH-001-D mindspeed technologies ? 9 preliminary information / mindspeed proprietary and confidential preliminary information 3.3 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 r shunt = 39 ? , c shunt = 3.9 pf. these values will need to be optimized fo r 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 figure 3-1 . 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. r modset determines the modulation current according to the following formula: i mod = 350/r modset figure 3-2 shows the modulation current for a given r modset resistor. figure 3-2. modulation current vs. r modset modulation current in ma 0.00 10.00 20.00 30.00 40.00 50.00 60.00 70.00 80.00 90.00 0 10203040 rmodset (kohms) imod (ma)
functional description 02066-DSH-001-D mindspeed technologies ? 10 preliminary information / mindspeed proprietary and confidential preliminary information 3.4 mean power control loop 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 phot ocurrent. 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 (r mpcset ) sets the optical power. r mpcset = 1.28/i pin i pin 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 c mpc . in some applications the internal capacitance at c mpc may be sufficient and an external c mpc will not be required.

functional description 02066-DSH-001-D mindspeed technologies ? 11 preliminary information / mindspeed proprietary and confidential preliminary information 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 bi as current generated by the m02060. the bias current limit is set by an external resistor to ground, r oca . when this limit is exceeded the oca pin is asserted low. figure 3-4 shows the maximum bias current limit vs r oca . 3.5 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 (r oca ) from the oca set pin. when the bias current limit is reached alarm flag oca is asserted low. a loop failure alarm is also pr ovided to detect when the bias current can no longer be adjusted to achieve the desired average optical power. 3.6 data input latch to minimize input data pattern-dependent jitter, a differenti al 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 th e internal circuitry. when this latch function is not used, connect clk+ to v cc and leave clk- unconnected. 3.7 enable control 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. figure 3-4. typical limiting current vs r oca (at 25 c) 0 10 20 30 40 50 60 70 80 90 100 0 10000 20000 30000 40000 r oca ( ? ) i oca (ma)
functional description 02066-DSH-001-D mindspeed technologies ? 12 preliminary information / mindspeed proprietary and confidential preliminary information 3.8 current monitors the m02066 features bias and modulation current monitor outputs. the bias mon output sinks a current equal to nominally 1/60 of the laser bias current (i bias ). the mod mon output sinks a current equal to nominally 1/60 of the laser peak to peak modulation current (i mod ). bias mon and mod mon should be connected through a pull-up resistor to v cc . choose a pull-up resistor value that ensures a voltage at bias mon greater than v cc -1.6v and a voltage at mod mon greater than v cc - 1.0v. these pins should be tied to v cc if not used. 3.9 temperature compensation the reduction in slope efficiency of typical laser diodes caused by increased temperature can be compensated by utilising the tc start and tc slope features of the m02066. under closed loop conditions the average optical power will be maintained by the mean power control loop, compens ating for factors such as temperature and age. however, as the laser slope efficiency reduces with incr easing temperature the lase r 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 (tc start ) at which the compensation begins to take effect is set by a resistor (rtc start ) from the tc start pin to ground. the rate of increase of modulation current with temperature (beyond tc start ) is set by a resistor (rtc slope ) from the tc slope 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 tc slope is programmable, tc start is connected to 0 v. figure 3-5. typical eye diagram 2.5 gbps optical eye @ -3 dbm (1.87 ghz filter)
