Dual 16-bit, 1.6-GSPS, TxDAC+ D/A Converter Synthesizes High-Quality Wideband Signals from Baseband to High Intermediate Frequencies

ADI's AD9142 D/A converter features a proprietary low spurious and distortion design with on-chip, numerically-controlled oscillator and integrated interpolation filters.

NORWOOD, Mass.--(BUSINESS WIRE)-- Analog Devices, Inc. (ADI), a global leader in high-performance signal processing technology and the data converter market share leader*, today introduced the AD9142 dual-channel, 16-bit, 1.6-GSPS D/A converter, which supports high data rates and complex modulation schemes required in communications, test and instrumentation, and defense and aerospace systems.


Featuring an on-chip 32-bit NCO (numerically-controlled oscillator) that allows flexible placement of the IF (intermediate frequency) carrier to optimize system performance, ADI's AD9142 D/A converter exceeds requirements for applications that use sophisticated DPD (digital pre-distortion) techniques demanding broad signal bandwidths.

The combination of programmable interpolation rate, high sample rates, and fine NCO modulation capability gives system designers flexibility when choosing D/A converter output frequencies. This is especially helpful in meeting four- to six-carrier GSM transmission specifications and other communications standards. Operating with the on-chip PLL (phase-locked loop) at a D/A converter output frequency of 200 MHz, the AD9142 delivers a 79-dB ACLR (adjacent-channel leakage ratio) for six-carrier GSM applications.

The AD9142 includes integrated interpolation filters with selectable interpolation factors of 2, 4, and 8. The dual D/A converter data interface supports word and byte load allowing customers to reduce input pins on lower data rates to save board space, power and cost. The AD9142 is available in a space-saving 72-pin LFCSP (lead-frame chip-scale package).
