Analog Devices' Integrated Wideband, Multi-Carrier Receiver Enables Major 3G Cellular Standards

Analog Devices

MxFE® device integrates the industry's highest performance 14-bit ADC with a six-channel digital down- converter for multi-carrier signal processing.

November 04, 2003- Analog Devices Inc. introduced a wideband receiver subsystem for cellular base stations that addresses the demanding performance requirements of 3rd generation (3G) standards, such as CDMA2000, UMTS, and TD-SCDMA.

About the AD6654
Analog Devices' new mixed-signal device the AD6654 combines the industry's highest performance 14-bit analog-to-digital converter (ADC) with a four- or six-channel digital down-converter (DDC). This highly integrated solution enables efficient processing of multi-carrier standards by removing the traditional interconnect issues associated with high-speed data transfer from the ADC to the DDC. In addition, the integrated device reduces the bill of material (BOM) components count, which can translate into a 20 percent saving in cost over individual components.
AD6654
The AD6654 joins ADI's MxFE® (mixed-signal front-end) family of high-speed converters. MxFE devices are based upon a "smart partitioning" of analog and digital functions to provide optimum cost and performance combinations. The analog core of the AD6654 contains ADI's industry-leading high-speed 14-bit ADC (the AD6645), which operates at more than 92 MSPS, while the digital function is performed by a DDC.

Pricing and Availability The AD6654 is sampling now, and production quantities will be available in the first quarter of 2004. The device is available in a 256-lead BGA (ball grid array) package and is priced at $75.24 in 10,000-piece quantities for the six-channel version and at $68.66 in 10,000-piece quantities for the four-channel version.
