9 / 20 page 2000 Feb 21 9 Philips Semiconductors Product specification Satellite demodulator and decoder TDA8044 Pin compatibility The TDA8044 is backwards pin compatible with the TDA8043, this means that the functional pins of the TDA8043 have been left unchanged on the TDA8044. However due to extra functionality of the TDA8044, some of the not connected pins of the TDA8043 have become functional pins on the TDA8044. Table 1 lists the modified pins of the TDA8044. Table 1 Modified pins of the TDA8044 If it is required to replace the TDA8043 with the TDA8044 and the pins with extra functionality are not required, then the following measures on the PCB layout must be taken to avoid I/O conflicts in the TDA8044: • Pin numbers 4, 5, 26, 27, 36, 37, 47, 65, 92, 93 and 95 must be put to ground • Pin numbers 39, 64 and 91 must be left not connected. With these measures it is possible to use the TDA8043 and the TDA8044 on the same PCB without any problems. In order to use pins with the extra functionality of the TDA8044, PCB layout changes are necessary.
