TD1600ALF-4

Tuner module for digital terrestrial (OFDM) applications

Rev.c 鈥?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 frequency 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.
