Note
The shaded D/A converter outputs indicate frame data. t1=132ns, t2=396ns, t3=528ns, t4=176ns, t5=308ns, t6=352ns,
t7=220ns, t8=616ns, and t9=484ns
A/D Converter Interface
The PIP controller interfaces with an LC7480 multiplex-
ing A/D converter using the AD0 to AD5 and VREF
inputs and CLAMPAD, YSW, RSW, BSW and ADCLK
outputs. The LC7480 converts the Y, R – Y and B – Y
video signals into 6-bit digital data which is input to the
PIP on AD0 to AD5. YSW, RSW and BSW control the
LC7480 input multiplexer. The conversion sequence is Y,
R – Y, Y, B – Y, as shown in the following figure. The
conversion frequencies are shown in the following table.
The LC7441 and LC7480 should be mounted as closely
as possible and care taken with the PCB layout because
of the high signal frequencies.
