The AN33215S brightness signal processing integrated circuit is produced by the Panasonic company that can be used in the Panasonic AN-M series cameras. 1.Features The AN3215S's main function: it amplifies and modulates the FM brightness signal which is sent from the video magnetic head amplifier when it is replaying, and it reverts the FM brightness signal to the brightness signal, then the brightness signal composes of the video signal with the chroma signal. When it is recording, it AGC amplifies, black and white cute, and clamps the video signal to change it into the FM signal, this FM signal adds to the magnetic head amplifier to supply the recording signal for the video magnetic head. 2.Pin functions and data The AN3215S uses the 28-pin dual-row plastic structure, the pin functions and data are as shown in table 1. Table 1 The pin functions and data of the AN3215S 3.Typical application circuit The internal circuit block diagram and the typical application circuit are as shown in figure 1. Figure 1 The internal circuit block diagram and the typical application circuit of the AN3215S
