MAX3541 pdf datasheet (变频电视调谐器

The MAX3541 complete single-conversion television
tuner is designed for use in analog/digital terrestrial applications
and digital set-top boxes. This television tuner
draws only 760mW of power from a +3.3V supply voltage.
The MAX3541 is designed to convert PAL or DVB-T signals
in the 47MHz to 68MHz, 174MHz to 230MHz, and
470MHz to 862MHz bands to an intermediate frequency
(IF) of 36MHz.
The MAX3541 includes a variable-gain low-noise amplifier
(LNA), multiband tracking filters, a harmonic-rejection
mixer, a low-noise IF amplifier, an IF power detector, and
a variable-gain IF amplifier. The MAX3541 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 dualconversion
tuner solutions.
The MAX3541 is specified for operation in the -40°C to
+85°C temperature range and is available in a leadless
48-pin flip-chip (fcLGA) package.
