Preliminary specification
Integrated VIP and teletext decoder
(IVT1.1X)
SAA5254
Notes
1.
This current is the maximum allowed into the inputs when line and field flyback signals are connected to these inputs.
Series current limiting resistors must be used to limit the input currents to
±
1 mA.
RGBREF is the positive supply for the RGB output pins and it must be able to source the I
OH
current from the
R, G and B pins. The leakage specification on RGBREF only applies when there is no current load on the RGB pins.
