The optical output power of the laser diode is set-up by means of an external resistor (RMD/PMD). For laser current control without a monitor diode, the laser current monitor at pin IMON is utilised. For high pulse frequencies the device can be switched into controlled burst mode. A previously settled operating point is maintained throughout the burst phase. An averaging current monitor can be set by an external resistor at pin RSI. When the current limit is reached, overcurrent is signalled at NERR and the current from pin VCCA is limited to the pre-set value but the iC is not shut down. There is an additional current limitation in pin LDA that prevents the iC from overpowering the laser diode. Setting pin NSLP low, the iC enters a low consumption sleep-mode (< 50 µA typ.).

The control is enabled with pin REGE set to high. With AVG set to low, the peak power control is enabled. The laser power level is selected by means of the resistor RMON (= RMD + PMD). This control mode can be used for frequencies up to ca. 4 Mhz. For higher frequencies the averaging control (AVG = high) or the burst mode have to be used. Tables 4 and 5 show how to set the inputs for laser control depending on the input interface selected (TTL or LVDS).

RMON must be chosen in a way that the monitor current generated by the desired output power creates a voltage drop across RMON of 250 mV (cf. Electrical Characteristics No. 201). Averaging control (AVG = high): In this mode the calculation is the same as in peak control, only the result has to be divided by the duty cycle of the laser pulses, D = Tτ . At a duty cycle of e.g. 50% D = 21 . ar y n i im prel iC-NZP P-TYPE LASER DIODE DRIVER Rev A1, Page 8/13 Control modes Averaging Operation mode RMON calculation AVG = 0 Peak control RMON = AVG = 1 Averaging control RMON = V (MD) IM V (MD) IM×D Table 6: RMON dimensioning Example By way of example, an output level of 1 mW is to be set. With an optical power of 1 mW e.g. laser diode HL6342G has a typical monitor current (IM) of 15 µA. The following value is then obtained for the resistor at pin MD (RMON = PMD + RMD, where RMD is a fixed resistor and PMD a potentiometer.): RMON = Best performance recommendations The operating point for the laser diode is stored in an on-chip capacitor. This permits a fast start-up but can lead to an unstable control circuit under certain conditions such as inadequate PCB layout or laser with very low monitor current. In that cases, an external capacitor is to be connected as close as possible to the chip, across pin CI and CIS. This will prevent instability of the control circuit. For averaging control a 10 nF capacitor at CI is recommended. Special care must be taken in PCB layout when laying out the path from the laser diode’s cathode to GND. This path must be kept as short as possible to avoid parasitic inductances. A snubber network across the laser diode also helps to compensate for these parasitic inductances. 0.25 V V (MD) = = 16.67 k Ω IM 15 µA External capacitor mode In applications where an external capacitor is required (see best performance recommendations below), the external capacitor mode must be enabled (pin NCID = low).

Figure 6: iC-NZP VDDA current limitation Short pulses at VDDA with higher currents are possible as only the DC current is monitored and capacitor CVDDA supplies the current for short pulses. BURST MODE In controlled burst mode iC-NZP can pulse with up to 155 MHz. Controlled here means that a pre-set operating point is maintained during the burst phase. Therefore an operating point is settled first, for which pin REGE has to be high and the laser must be switched on. Once the operating point has been reached the laser can be switched off again. The operating point is stored in an on-chip capacitor and when REGE is set to low, the burst mode is activated. The pre-set operating point is maintained. To prevent the laser current from rising due to residual currents, the capacitor is discharged with a maximum of 150 nA (cf. Electrical Characteristics No. 405). For a longer burst mode, an external capacitor can be connected to pin CI. As the capacitor is discharged gradually, the output level must be re-settled again after a certain period, depending on the admissible degradation of the laser output power. CURRENT CONTROL The iC-NZP also supports laser current control, when no monitor diode is present. For that purpose, a fraction of the current flowing trough the laser is provided at IMON pin (ILDA / 280, cf. Electrical Characteristics Control modes Averaging Operation mode No. 406). The laser current is set by means of resistor RMON (= RMD + PMD). Figure 7 shows the typical set-up for current control.
