MAX3540 pdf

The MAX3540 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 MAX3540 is designed to convert NTSC or ATSC sig-
nals in the 54MHz to 860MHz band to a 44MHz interme-
diate frequency (IF).
The MAX3540 includes a variable-gain low-noise ampli-
fier (LNA), multiband tracking filters, a harmonic-rejec-
tion mixer, a low-noise IF amplifier, an IF power detector,
and a variable-gain IF amplifier. The MAX3540 also
includes fully monolithic VCOs and tank circuits as well
as a complete frequency synthesizer. This highly inte-
grated design allows for low-power tuner-on-board
applications without the cost and power-dissipation
issues of dual-conversion tuner solutions.
The MAX3540 is specified for operation in the 0°C to
+85°C temperature range and is available in a leadless
48-pin flip-chip (fcLGA) package.
