MAX3543 Silicon tuner eliminates spurs in analog and digital TV reception

Hybrid tuner enables superior reception, saves space, and simplifies design.

Maxim unveils a silicon tuner with an innovative single-conversion architecture that enables spur-free reception of analog and digital signals, thus reducing implementation complexity.

SUNNYVALE, CA—April 15, 2010—Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX3543, 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, this device offers best-in-class tuner performance using a standard IF architecture that ensures < -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% reduction in space and 25% 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, 6mm x 6mm, 40-pin TQFN package, and is fully specified over the 0°C to +70°C temperature range. Prices start at $6.95 (1000-up, FOB USA). An evaluation kit is available to speed designs.

Maxim Integrated Products is a publicly traded company that designs, manufactures, and sells high-performance semiconductor products. The Company was founded over 25 years ago with the mission to deliver innovative analog and mixed-signal engineering solutions that add value to its customers' products.
