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 RAVR and
RER. 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.
