Preliminary specification
PAL/NTSC encoder
TDA8501
PAL/NTSC and Y/Y + SYNC
Pin 17 is used as a four level control pin to condition the Y/Y + SYNC input signal (via pin 5). Pin 17 is normally connected
to ground for PAL mode, or to V
CC
for the NTSC mode. By use of external resistors (potential divider connected to
pin 17), the input blanking at pin 5 can be switched on and off. (see Table 1 and Fig 14).

PAL/NTSC Y/Y +SYNC pin 5 options (pin 17 connection configurations).
LIMITING VALUES
In accordance with the Absolute Maximum System (IEC134); all voltages referenced to V
SS
(pin 10).
