Press Release Summary:
Featuring 1 GSPS data rate, AD9148 supports multi-antenna wireless communications standards requiring bandwidths demanded by digital pre-distortion transmit systems. Supplied in 12 x 12 mm package, this 4-channel, 16-bit DAC features on-chip 32-bit numerically controlled oscillator; 2X, 4X, and 8X interpolation; and dual-port, time-interleaved LVDS interface with single port or byte-mode support. Unit also features 8-deep FIFO memory and on-chip support for multi-DAC synchronization.
Original Press Release:
Industry's First High-Speed Quad Digital-to-Analog Converter Yields Higher Performance and Design Efficiency in Wireless Base Stations
ADI's 1-GSPS quad-channel DAC is an industry first at this speed and integration level; reduces PCB area by 20 percent compared to dual-channel options.
NORWOOD, Mass.--Analog Devices, Inc. (ADI), the global leader in data-conversion technology, introduced today the industry's first high-speed quad DAC (digital-to-analog converter) to provide support for multi-antenna wireless communications standards requiring the large bandwidths demanded by DPD* (digital pre-distortion) transmit systems. The four-channel, 16-bit DAC has a 1-GSPS (giga-sample per second) data rate and cuts component count in half relative to dual-channel DACs. Its 12 mm x 12 mm package size allows designers of WCDMA, CDMA2000, TD-SCDMA, GSM and WiMax infrastructure equipment and other wireless applications to reduce PCB (printed circuit board) space by 20 percent.

AD9148 Key Features and Benefits
As part of a complete signal chain, the AD9148 quad DAC can interface to ADI's ADL5371/2/3 frequency modulators, ADL5375 and ADRF670x analog quadrature modulators and AD9516 clock IC for clock distribution.

DAC Data Pattern Generator Tool Available
ADI's Data Pattern Generator (DPG2) is a bench-top instrument for driving vectors into Analog Devices' high-speed digital-to-analog converters. The DPG2 connects to a PC over USB and allows a user to download a vector from their PC into the DPG2's internal memory. Once downloaded, the DPG2 can run the vector at full speed via an attached evaluation board for a specific DAC. This allows for rapid evaluation of the DAC with both generic and customer-generated test data.

* Digital pre-distortion is an advanced signal processing technique that corrects for nonlinearities in radio transmit paths, allowing power amplifiers to run at higher efficiency levels with less distortion.
** A numerically controlled oscillator is used to provide frequency translation in the digital domain-- an important block in modern digital radio processing.
