PIN FUNCTION DESCRIPTION (continued)
Equivalent Internal Circuit
Description
This pin is used in conjunction with the RGB OSD
VCC inputs. It is a high speed switch used for overlaying
text on picture. A logic low selects Pins 2, 4, 6. A logic
high selects Pins 8, 10, 12.

The video outputs are configured as emitter–followers
VCC with a driving capability of about 15 mA each.
The dc voltage at these three emitters is set to 1.2 V
(black level).
RE = 330
Typical
The dc current through the output stage is determined
by the emitter resistors (typically 330 Ω).

A 100 nF capacitor is connected to each of these pins.
The capacitor is used for video output dc restoration.
Connect to 8.0 V dc supply, ±5%. This VCC is for the
video output stage. It is internally connected to the
collectors of the output transistors.
5.0 V regulator. Minimum 10 µF capacitor is required
for noise filtering and compensation. It can source
up to 20 mA but not sink current. Output impedance
is ≈ 10 Ω. Recommended for use as a voltage
reference only.
