AGC (Auto Gain Control) function

GCA (Gain Control Amplifier) is built in, it is combination with a digital AGC function, and it is possible to use an AGC

function to a CVBS input and Y input.

There are two kinds of AGC functions, AGC auto mode and manual gain mode.

If a GCA function is used, the 1.0 Vp-p standard input of CVBS will become possible.

5.2.5

LPF (Low Pass Filter) function

LPF for Anti-alasing is built in the preceding paragraph of GCA, and ON and through channel selection can be

performed.



System : 4th Butterworth filter



Frequency characteristic : -1 dB @6 MHz, -14 dB @13.5 MHz (design value)
