com KIT ATION EVALU E L B A IL AVA Complete Single-Conversion Television Tuner Features o Low Power Consumption: 760mW (typ) from a +3.
3V Supply Voltage o Integrated Tracking Filters o Low Noise Figure: 4.
9dB (typ) o Small 7mm x 7mm fcLGA Lead-Free Package o IF Overload Detector Controls RF Variable-Gain Amplifier o 2-Wire, I2C-Compatible Serial Control Interface General Description The MAX3542 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 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 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 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 (fcLGA) package.
