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.

20 Dec 12 - Norwood, MA
  • 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.

    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).
