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)
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
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
Pricing, Availability and Complementary Products
Complementary ADI components include the ADL537x
series quadrature modulators, and the AD9516
14-output clock generator IC.
