General Description
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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
