TDA4660, TDA4660V2 integrated block internal box circuits
2.Pin functions and data The TDA4472 is in the 28-pin dual in-line package, the pin functions and data is as shown in table 10. Table 10 The pin functions and data of the TDA4472 circuit TDA4601--Thick-film switch power supply integrated circuit The TDA4601 is designed as the thick-film switch power supply integrated circuit that is produced by the PHILIPS company, and it can be used in various types of large screen color TV and computer monitor switch power supply circuit. TDA4660, TDA4660V2--The baseband delay IC The TDA4660 and TDA4660V2 are designed as the baseband delay IC which is produced by the PHILIPS company, and it can be used in variety of multi-system color TVs. 1.Features The TDA4660 and TDA4660V2 can process the positive and negative color difference input signals, and clamp the fused AC input signal ±(R-Y) and ±(B-Y); and lock the 3MHz internal clock signal by the sand castle pulse (64us cycle), the 3MHz internal clock signal is from the internal 6MHz Vcc divided-frequency. The integrated block internal box circuit is as shown in figure 10.
