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 frequency is fed through one of the pinnd 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 ……
