Notes
1. At
40 °C the value of VCMFB should be not become lower than 0.85 V.
2. Closed-loop output impedance (10 k
between pins RFEQO and RFFB).
3. GRF =(GRFEQO at fEQ) (GRFEQO at f = 1 kHz) where:
a) fEQ = 720 kHz for n = 1 times speed (see Fig.5)
b) fEQ = 1440 kHz for n = 2 times speed (see Fig.6)
c) fEQ = not applicable for n = 4 times speed (see Fig.7).
4. The appropriate external filter (n = 1, 2 or 4) should be used (see Table 1).
5. Values to be used in equation (1).
6. Vdrop =VDD(L) Vo(LASER).
7. An external resistor can be used to reduce the maximum output current (and the gain) of the laser supply;
see equation (4).
8. The output impedance strongly depends on the drop voltage (Vdrop). The output impedance will approximately double
when the drop voltage doubles.
9.
10. When a voltage dip at VDD(L) occurs it could cause peak currents on Io(LASER) coming out of the ALPC output.
To protect the laser against such peak currents a protection circuit will switch-off the laser current when Vdrop
becomes lower than Vclamp. When Vdrop >Vclamp the laser will switch-on automatically again.
11. The pin EQSEL is a three level switch. When this pin is left open-circuit two internal resistors will keep the pin EQSEL
at 1
2VDD. This is the n = 4 times speed state. The two internal resistors are non-linear (when EQSEL = HIGH or LOW
the input or output current will be limited).
