In ADV740x referent schematic there is voltage divider formed by 19ohm and 56ohm resistor. Why is necesery to reduce CVBS sigal amplitude?
Thanks In Advance
The 19 + 56 ohm provides the needed 75 load impedance to match the 75 Ohm CVBS cable and the ADV760x analog inputs are designed to handle ~0.8Vpp signals, not the 1Vpp signal on the input.
