MAX3541

19-1029; Rev 0; 10/07 Complete Single-Conversion Television Tuner www.datasheet4u.com General Description Features ♦ Low Power Consumption: 760mW (typ) from a +3.3V Supply Voltage ♦ Integrated Tracking Filters ♦ Low Noise Figure: 4.9dB (typ) ♦ Small 7mm x 7mm fcLGA Leadless Package ♦ IF Overload Detector Controls RF Variable-Gain Amplifier ♦ 2-Wire, I2C-Compatible Serial Control Interface MAX3541 The MAX3541 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 MAX3541 is designed to convert PAL or DVB-C signals in the 47MHz to 68MHz, 174MHz to 230MHz, and 470MHz to 862MHz bands to an intermediate frequency (IF) of 36MHz. The MAX3541 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 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 dualconversion tuner solutions. The MAX3541 is specified for operation in the -40°C to +85°C temperature range and is available in a leadless 48-pin flip-chip (fcLGA) package.
