Complete Single-Conversion Television Tuner

The MAX3540 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 MAX3540 is designed to convert NTSC or ATSC signals in the 54MHz to 860MHz band to a 44MHz intermediate frequency (IF).

The MAX3540 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 MAX3540 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 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.
