TDA7315D0l3TR--Sound Field Control/Analog Surround Processing IC The TDA7315D0l3TR is designed as one kind of Sound Field Control/Analog Surround Processing IC which is produced by the PHILIPS company, and it can be used as the tone and surround sound signal processor of the new large-screen color TV. The TDA7315D0l3TD is composed of the R, L-channel audio processor, the I(2)C bus interface and other circuits. This Ic is in the 20-pin dual in-line package. The pin functions and data is as shown in table 39. Table 39 The pin functions and data 1.Features The TDA9181 has the features of high integration, few external components, low voltage and low power consumption.etc, it has two 1H/ZH delay lines for the NTSC or PLA comb filter, this multi-standard comb filter supports PALB, G, H, D, I, M, N and NTSC systems. It has the Y/CVBS input circuit to choice the output signal is CVBS siganl or Y/C signal; it also has the output selection circuit to choice the input signal is CVBS siganl or Y/C signal. The integrated block internal box circuit is as shown in figure 39.
