Page 12: Description Of Block Diagram
DESCRIPTION OF BLOCK DIAGRAM 1. Scaler One chip IC(GMZAN1, U3) GMZAN1 (U3) is one chip IC which it supports four internal function blocks of Video Amp, PLL, A/D converter and Video processor. Video signal (0.7Vp.p) clamped through C44, 45, 191 with matching IC’s proper cut off voltage. This signal is processed as a proper 8 bit digital signal by U3’s amplifying, phase locking, A/D converting, and scaling operations. -
