Product Summary
The TD1611ALF/IHP-452 is a terrestrial tuner designed to cope with digital COFDM and analog transmission standards. From function point-of-view the TD1611ALF/IHP-452 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 of the TD1611ALF/IHP-452 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.
Parametrics
TD1611ALF/IHP-452 absolute maximum ratings: (1)Frequency ranges: 174 to 230 MHz; (2)RF power gain: 47 to 50 dB; (3)Overall gain taper: 6 dB; (4)RF AGC range Low band: 40 dB, Mid band: 40 dB, High band: 35 dB; (5)Image rejection (Referred to IF-center frequency) VHF high (mid band): 66 to 70 dB, UHF (high band): 55 to 60 dB; (6)ESD protection of terminals: 2 kV; (7)Surge protection at RF-input: 5 kV.
