Table 3:
The TDA8263HN contains the core of the RF analog part of a digital satellite receiver. The
signal coming from the LNB is coupled to the RF inputs. The internal circuitry performs the
Zero-IF quadrature frequency conversion and two in-phase (IP/IN) and two quadrature
(QP/QN) output signals can directly be used to feed a Satellite Demodulator and Decoder
circuit (SDD). Low-pass filter cut-off frequency can be adjusted from 5 MHz to 36 MHz in
32 steps. This allows a large flexibility in the SDD input. 10 gain values are present at
output amplifier to compensate cut-off frequency adjustment and single output
application.
The IC gain controlled amplifier before the mixer is controlled by the SDD through pin
AGC.
An input level detector gives the wide band RF level. This information is available through
