30 Mbits/s up to 1.25 Gbits/s laser drivers TZA3047A; TZA3047B
12.3 TZA3047B with dual-loop control
A simplified application using the TZA3047B with dual-loop control and with a DC-coupled laser at 3.3 V or 5 V laser
voltage is illustrated in Fig.8. The average power level and the extinction ratio are determined by the resistors R
AVR
and
R
ER
. The MODOUT and BIASOUT outputs are connected to the MODIN and the BIASIN inputs respectively.
The open-drain outputs ALOP and ALMON are short-circuited with pin ENABLE causing an active alarm to disable the
bias and modulation current sources. The ALRESET input will reset the alarm latches and enable normal operation.

12.4 TZA3047B with average loop control
A simplified application using the TZA3047B with average loop control and a DC-coupled laser at 3.3 or 5 V laser voltage
is illustrated in Fig.9. The ER pin is short-circuited to ground for the average loop control. The average power level is
determined by the resistor R
AVR
. The average loop controls the bias current and the BIASOUT output is connected to
the BIASIN input. The modulation current is determined by the MODIN input voltage which is generated by the resistor
R
MODIN
and the 100 µA source current of the MODIN pin.

13 BONDING PAD LOCATIONS
Notes
1. All coordinates are referenced (in µm) to the centre of
the die.
2. All GND connections should be used.
3. Recommended order of bonding: all GND first, then
V
CCA
, V
CCD
and V
CCO
supplies and finally the input
and output pins.
4. Pad is internally connected, do not use.
