    DESCRIPTION OF BLOCK DIAGRAM 1. Scaler One chip IC(GMZAN-2, U201) GMZAN-2 (U201) 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 C207, 208, 209 with matching IC’s proper cut off voltage. This signal is processed as a proper 8 bit digital signal by U201’s amplifying, phase locking, A/D converting, and scaling operations.
