19-0848; Rev 0; 10/07 KIT ATION EVALU LE B A IL A AV plete Single-Conversion Television Tuner .. General Description Features - Low Power Consumption: 760m W (typ) from a +3.3V Supply Voltage - Integrated Tracking Filters - ATSC A/74 pliant - 40d B Adjacent Channel Protection Ratio (ACPR) - 4.4d B (typ) Low Noise Figure - Small, 7mm x 7mm, fc LGA Leadless Package - 256-QAM-patible Phase-Noise Performance - IF Overload Detector Controls RF Variable-Gain Amplifier - 2-Wire I2C-patible Serial Control Interface The MAX3540 plete single-conversion television tuner is designed for use in analog/digital terrestrial applications and digital set-top boxes. This television tuner draws only 760m W 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 plete 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 (fc LGA) package.
