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).
