The ANADIGICS DBS (Direct Broadcast Satellite) Tuner IC is intended for use in high volume, low
cost manufacturing of compact DBS tuners for satellite receivers and integrated satellite ready
TV/VTR receivers.
The ADC20013 Tuner IC provides DBS tuner manufacturers the ability to produce, in high volumes,
tuners with low component count, minimal tuning, small size, high reliability and exceptional price-
performance ratios.
The ADC20013 offers a high degree of functionality in a very small and user friendly configuration.
