INTEGRATED CIRCUITS DATA SHEET TDA8725T Antenna signal processor 1995 Mar 21 Product specification File under Integrated Circuits, IC02 Philips Semiconductors Philips Semiconductors Product specification Antenna signal processor TDA8725T For PIP applications, the antenna input signal is split and FEATURES fed to the main TV tuner and the PIP tuner. Good signal • 75 ? antenna input stage suppression between the two outputs enables good quality • 75 ? VCR RF input stage of the main picture when the PIP tuner is in use. • 75 ? VCR tuner output For VCR applications, the antenna input signal is split and • 75 ? TV tuner output. 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
