7.4
The settings of all internal switches, DACs and modes of
operation can be programmed via the serial bus. There are
also a few external digital signals which influence the
programmed settings.
7.4.1
To ensure a safe start-up, the TZA1038HW has an internal
Power-on reset that resets on bit PWRON. During
STANDBY mode, most circuits, including laser supplies,
are switched off.
7.4.2
The servo outputs can be disabled for easy interfacing in
systems where two front-end signal processors are used.
This mode will set the outputs OA to OD, S1 and S2 to
3-state. The RF data path remains active.
