Table 1 TV receiver versions SDIP56 PACKAGE TV RECEIVERS ECONOMY PAL only PAL/NTSC (SECAM) NTSC TDA8374B TDA8374 and TDA8374A TDA8373 MID/HIGH END - TDA8375 and TDA8375A TDA8377 and TDA8377A GENERAL DESCRIPTION
The various versions of the TDA837x series are I2C-bus controlled single-chip TV processors which are intended to be applied in PAL/NTSC (TDA8374 and TDA8375) and NTSC (TDA8373 and TDA8377) television receivers. All ICs are available an SDIP56 package and some versions are also available a QFP64 package. The ICs are pin compatible so that with one application board NTSC and PAL/NTSC (or multistandard together with the SECAM decoder TDA8395) receivers can be built. Functionally this IC series is split to 2 categories: Versions intended to be used in economy TV receivers with all basic functions Versions with additional functions such as E-W geometry control, horizontal and vertical zoom function and YUV interface which are intended for TV receivers with 110° picture tubes. The various type numbers are given in Table 1. The detailed differences between the various ICs are given in Table 2.

TLV320AIC15CDBT : Voice-Band Codecs. ti TLV320AIC15, Single Channel Codec. Texas Instruments (TI) has recently identified a problem in the product models listed above related to DLL clock-generation. When a clock-generation mode is used that powers up the delay-locked-loop (DLL), the DLL may not startup properly when initiated, resulting in the audio master clock not functioning. This results in the codec in the products not functioning.
