Complete Single-Conversion Television Tuner

MAX3540

General Description

Features

The MAX3540 complete single-conversion television

tuner is designed for use in analog/digital terrestrial appli-

cations and digital set-top boxes. This television tuner

draws only 760mW of power from a +3.3V supply voltage.

♦ Low Power Consumption: 760mW (typ) from a

+3.3V Supply Voltage

♦ Integrated Tracking Filters

♦ ATSC A/74 Compliant

The MAX3540 is designed to convert NTSC or ATSC sig-

nals in the 54MHz to 860MHz band to a 44MHz interme-

diate frequency (IF).

♦ 40dB Adjacent Channel Protection Ratio (ACPR)

♦ 4.4dB (typ) Low Noise Figure

The MAX3540 includes a variable-gain low-noise ampli-

fier (LNA), multiband tracking filters, a harmonic-rejec-

tion 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 inte-

grated design allows for low-power tuner-on-board

applications without the cost and power-dissipation

issues of dual-conversion tuner solutions.

♦ Small, 7mm x 7mm, fcLGA Leadless Package

♦ 256-QAM-Compatible Phase-Noise Performance

♦ IF Overload Detector Controls RF Variable-Gain

Amplifier

♦ 2-Wire I C-Compatible Serial Control Interface

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.
