Silicon tuner eliminates spurs in analog and digital TV reception
Maxim just introduced 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 degrees Celsius to +70 degrees Celsius temperature range. Prices start at $6.95 (1000-up, FOB USA). An evaluation kit is available to speed designs.
