TD1311ALF-4 fiche technique
TD1600ALF-4
Tuner module for digital terrestrial (OFDM) applications
Rev.c — 23-04-2007
Preliminary data sheet
1. General description
TD1600ALF-4 belong to the new generation of terrestrial tuners designed to cope with
digital COFDM and analog transmission standards.
From function point-of-view these tuners can be divided into two high-frequency
sections, a RF-loopthrough and a single conversion tuner part.
In the loopthrough section broadband low-noise amplifiers are used. The loopthrough
frequency response covers the entire frequency range from VHF to UHF.
The RF-downstream section is equipped with a state-of-the-art single conversion tuner,
which makes use of a highly integrated MOPLL IC that provides the required high level
of performance necessary for COFDM signal processing.
The tuners are provided with a DC/DC converter to generate the tuning voltage
internally.
The internal 4MHz PLL crystal reference freqnud ency is fed through one of the pin-
terminals and can be used as a clock for a 2 device e.g. the channel decoder.
Two IF-outputs are provided, one is a wideband, non filtered IF-output, while the other,
narrow-band IF-output is equipped with a SAW-filter and a gain controllable IF-amplifier.
This narrow-IF-output matches the A-to-D converter input of currently available channel
decoders.
All tuners out of this family can be equipped with two standard IEC-connectors, RF-in is
IEC-female, RF-out is IEC-male. The tuner housing is available in a vertical or
horizontal mountable execution; the pinning pitch corresponds to the World Standard
Pinning convention.
Apart from the RF-connectors, all other terminals are made with wire pins at the bottom
side of the tuner.
