STV2050A - ELECTRICAL CHARACTERISTICS
20.8 HORIZONTAL AND VERTICAL SYNCHRONIZATION INPUTS
20.9 TBU OUTPUTS
20.10 ELECTRICAL LOOP PADS
Notes:
1. PORA..C Input level can be latched in measuring line or with sys. clock.
2. PORA..C and OPTT input have digital inputs.
3. OPTI is only an input pin.
4. MLIN is only an output pin. It sends a pulse during the measuring line(M_Line, see ‘gain range control’). The signal can
