7-3-2. Video/Color Circuit

The video/color circuit consists of two ICs, QV005 (TDA9141: NTSC/PAL/SECAM DECODER), QV006 (TDA4665T: BASE BAND DELAY LINE), and supports each system of NTSC, PAL and SECAM.

Fig. 7-3-4 shows the pin configuration of TDA9141 and Fig. 7-3-5 shows the block diagram of TDA9141. Fig. 7- 3-6 shows the pin configuration of TDA4665T and Fig. 7-3-7 shows the block diagram of TDA4665T.
