The ADS5500, operating at 125 MSPS, features 70-dB SNR (signal-to-noise ratio) and 82-dB SFDR (spurious-free dynamic range) at 100-MHz input frequency. The low power dissipation reduces power supply requirements and the need for thermal management (cooling), resulting in smaller footprint and equipment size, and higher circuit density.

The performance of the ADS5500 allows wireless communications systems, such as base stations, to achieve higher receiver performance and handle more voice channels, thus allowing accurate reception of weaker, distant signals and reducing the number of analog signal chain components needed per base station. When combined with TI´s GC5016 digital up/down converter, the ADS5500 allows oversampling and undersampling of the input IF signal to improve signal quality and reduce circuit complexity. The ADS5500 is suitable for processing high input frequencies, such as 190 MHz, for undersampling applications.

The ADS5500 is sampling now, with volume production scheduled for 1Q 2004. The device comes in a 64-TQFP PowerPadTM package and is priced at $95 in 1,000 piece quantities (suggested resale pricing). Evaluation modules (EVMs) are also available.
