This television tuner draws only 760m W of power from a +3.3V supply voltage. The MAX3542 is designed to convert PAL or DVB-T signals in the 47MHz to 862MHz band to an intermediate frequency (IF) of 36MHz. The MAX3542 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 MAX3542 also includes fully monolithic VCOs and tank circuits, as well as a plete 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 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 (fc LGA) package.
