4.5 Front-End
The tuner support the full 1-45 MBaud DVB-S/S2 operating range and L-Band RF
input frequencies from 950MHz to 2150MHz , the baseband IQ analog waveforms
from the tuner sections are sampled by-bit A/D converter and processed by a
variable rate demodulator followed by a 24-tap equalizer and compliance with
DiSEqC2.x for communication with LNB and I2C protocol is used to control the
frequency and LNB.

8-bit A/D converters digitize the I and Q output of the tuner for processing by the
digital demodulator at a programmable sample rate of up to 135MHz
The AGC loop examines the power of the digitized signal and compare it to a
programmable loading factor
The I/Q imbalance correction loop compensates for quadrature imbalance introduced
by the direct conversion tuner.
Variable rate digital filters and matched filters will reduce demodulation error
