【Overview】TDA1827HD is a material conservative silicon tuner, specially suitable for application in mixed TV reception. Its structure includes selectable internal complete tuning function; Benefiting from its patented integrated loop through system structure, it can be used in multi-silicon tuner application.
It accumulates LNA (Low Noise Amplification, tracking filter device, mirror suppression mixer and IP wave filter system to process terrestrial RF TV signal while suppressing unwanted signal and convert it to low IF output.
The IF filter module support 6/7/8 MHz frequency bandwidth. TDA18271 only requires a single 16MHz crystal for clocking purpose. Clocked signal output can be used to realize and synchronize with the decoder unit or sent to a sub- tuner unit.
