Antenna Signal Processor

The TDA8725T has been designed to split and combine RF signals for Picture-In-Picture (PIP) and VCR applications. For PIP applications, the Antenna input signal is split and fed to the main TV Tuner and the PIP Tuner Good signal suppression between the two outputs enables good quality of the main picture when the PIP Tuner is in use. For VCR applications, the Antenna input signal is split and then fed directly to the VCR Tuner and the TV Tuner after being combined with the VCR - RF signal. Good signal suppression between the two outputs enables good quality pictures when the TV and VCR Tuners are both operating. Good signal suppression between the VCR input and the Antenna input reduces the amount of unwanted signal on the Antenna By NXP Semiconductors
