General Description
Features
The MAX3541 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.
o Low Power Consumption: 760mW (typ) from a
+3.3V Supply Voltage
o Integrated Tracking Filters
The MAX3541 is designed to convert PAL or DVB-T sig-
nals in the 47MHz to 68MHz, 174MHz to 230MHz, and
470MHz to 862MHz bands to an intermediate frequency
(IF) of 36MHz.
o Low Noise Figure: 4.9dB (typ)
o Small 7mm x 7mm fcLGA Leadless Package
o IF Overload Detector Controls RF Variable-Gain
Amplifier
The MAX3541 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 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 dual-
conversion tuner solutions.
o 2-Wire, I2C-Compatible Serial Control Interface
