FUNCTIONAL DESCRIPTION
The TZA3041AHL, TZA3041BHL and TZA3041U laser
drivers accept a 1.2 Gbits/s Non-Return to Zero (NRZ)
input data stream, and generate an output signal with
sufficient current to drive a solid state Fabry Perot (FP) or
Distributed FeedBack (DFB) laser. They also contain dual
loop control circuitry for stabilizing the true laser optical
power levels representing logic 1 and logic 0.

The input buffers present a high impedance to the data
stream on the differential inputs (pins DIN and DINQ);
see Fig.5. The input signal can be at a CML level of
approximately 200 mV (p-p) below the supply voltage, or
at a PECL level up to 800 mV (p-p). The inputs can be
configured to accept CML signals by connecting pins DIN
and DINQ to V
If PECL compatibility is required, the usual Thevenin
termination can be applied.
