ADI`s AD9142 D/A converter features a proprietary low spurious and distortion
design withon-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).
