FUNCTIONAL DESCRIPTION

The ML0XX18 is an external modulator driver integrating a D-FF and output waveform adjustment controls, such as

optical waveform on their system.

Figure 1 shows the block diagram of the ML0XX18.

DATA/CLOCK INPUT

Both the data and clock inputs have on-chip 50Ω terminations. Thanks to the high gain input buffers, the sensitivities of data

and clock inputs are as high as 200mV differential.

For the data input interface, both DC/AC-coupled connections are allowed. In the case of DC couple, keep IINBIAS floating

or connect to VEE in order to disable the internal biasing generator. If interfacing by AC couple, connect IINBIAS to GND, and

external DC blocking capacitors are required for AC couple.

The clock input supports only AC-coupled configuration. External DC blocking capacitors are needed as well.
