Fully integrated satellite tuner

Rev. 01 — 14 December 2004

Product data sheet

1. General description

The direct conversion QPSK demodulator is the front-end receiver dedicated to digital TV

broadcasting, satisfying both DVB-S and DBS TV standards. The wide range oscillator

(from 950 MHz to 2175 MHz) covers the American, European and Asian satellite bands,

as well as the SMA-TV US standard.

The Zero-IF (ZIF) concept discards traditional IF ﬁltering and intermediate conversion

techniques.

Gain-controlled ampliﬁers in the RF guarantee optimum signal level. The variable gain is

controlled by the signal returned from the Satellite Demodulator and Decoder (SDD) and

applied to pin AGC.

The integrated LNA allows the IC to be directly connected to the LNB output. The LNA can

be by-passed by an I²C-bus selectable attenuation, providing a 20 dB extra attenuation in

order to handle higher input signal levels of up to 0 dBm per channel.

Connected at the RF input, an RMS level detector provides through I²C-bus read mode

the full band input signal level.

The LO quadrature outputs are derived from a high performance integrated LC oscillator.

f _LO

Its frequency is:

^XTAL. Thanks to the low phase noise performance of the

--------------

---------

integrated LC oscillator which controls the LO frequency, the synthesizer offers a good

performance for phase noise in the satellite band. The step size of the LO output

frequency is equal to the comparison frequency.

Control data is entered via the I²C-bus. The bus can be either 5.0 V or 3.3 V, allowing

compatibility with most of existing microcontrollers.

An 8-byte frame is required to address the device and to program the main divider ratio,

the reference divider ratio, the charge-pump current and the operating mode.

A ﬂag is set when the loop is in-lock, readable during read operations, as well as the

Power-on reset ﬂag and RF input level.

The device has four selectable I²C-bus addresses. Applying a speciﬁc voltage to pin AS

selects an address. This feature gives the possibility to use up to four TDA8263HN ICs in

the same system.
