The MAX3542 complete single-conversion television
tuner is designed for use in analog/digital terrestrial appli-
cations and digital set-top boxes. This television tuner
draws only 760mW of power from a +3.3V supply voltage.
The MAX3542 is designed to convert PAL or DVB-T sig-
nals in the 47MHz to 862MHz band to an intermediate
frequency (IF) of 36MHz.
The MAX3542 includes a variable-gain low-noise amplifi-
er (LNA), multiband tracking filters, a harmonic-rejection
mixer, a low-noise IF amplifier, an IF power detector, and
a variable-gain IF amplifier. The MAX3542 also includes
fully monolithic VCOs and tank circuits, as well as a
complete frequency synthesizer. This highly integrated
design allows for low-power tuner-on-board applications
without the cost and power dissipation issues of dual-
conversion tuner solutions.
The MAX3542 is specified for operation in the 0°C to
+70°C temperature range and is available in a lead-free
48-pin flip-chip (fcLGA) package.
