NORWOOD, Mass. -- December 20, 2012

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).
