Abstract
A DBS receiver front end which includes a tuner chip and a demodulator/decoder chip having digital interface signals. The tuner chip is configured to receive the digital signals at a reduced peak-to-peak amplitude to reduce the digital interference noise in the tuner chip. The digital signals may also have a limited slew rate to further reduce the digital interference noise. The tuner chip is configured to convert a receive signal to a baseband signal, and the demodulator/decoder chip is configured to convert the baseband signal to a decoded signal.
