Silicon Tuner's Single-conversion Architecture Enables Spur-free Analog and Digital TV Reception

Maxim Integrated Products' MAX3543 is a broadband, multistandard silicon tuner for worldwide hybrid TVs, as well as terrestrial and cable set-top boxes. Developed using Maxim's high-performance BiCMOS process technology, the MAX3543 offers best-in-class tuner performance using a standard IF architecture that ensures less than -70dBc spurs. With the MAX3543, customers can use a single silicon pinout for all major worldwide television standards.

The MAX3543 enables the highest quality signal reception in demanding environments by offering best-in-class sensitivity, a 4dB noise figure, and superb blocker performance. The device directly addresses key market needs by exceeding can tuner performance and eliminating the unwanted spurs common in other silicon tuners. Meanwhile, its innovative design architecture eliminates the need for expensive external components such as SAW filters. This integration enables a 75 percent reduction in space and 25 percent reduction in cost over competing solutions, including can tuners. Implementation complexity is significantly reduced with a low-cost, single-sided, two-layer PCB design, which requires only minimal external components. The MAX3543 is packaged in a lead-free, 6x6mm, 40-pin TQFN package.
