TDA5051A NXP Semiconductors Home automation modem 8. Functional description Both transmission and reception stages are controlled either by the master clock of the microcontroller or by the on-chip reference oscillator connected to a crystal. This ensures the accuracy of the transmission carrier and the exact trimming of the digital filter, thus making the performance totally independent of application disturbances such as component spread, temperature, supply drift and so on.

TDA5051A NXP Semiconductors Home automation modem Remark: In transmission mode, the receiving part of the circuit is not disabled and the detection of the transmitted signal is normally performed. In this mode, the gain chosen before the beginning of the transmission is stored, and the AGC is internally set to −6 dB as long as DATA_IN is LOW. Then, the old gain setting is automatically restored. 8.
