Analog Devices, Inc. (Norwood, MA) introduced what it says is the industry’s fastest quad IF D/A converter. The AD9144 4-channel, 16-bit, 2.8-GSPS D/A converter supports high data rates and ultra-wide signal bandwidth enabling emerging wideband and multiband wireless applications. The AD9144 features 82-dBc spurious-free dynamic range (SFDR) and a maximum sample rate of 2.8 GSPS permitting multicarrier generation up to the Nyquist frequency. With -164 dBm/Hz noise spectral density, the converter enables higher dynamic range transmitters to be built. Its advanced and proprietary low SFDR and distortion design techniques provide high quality synthesis of wideband signals from baseband to high intermediate frequencies. A JESD204B eight-lane interface and low inherent latency of under two D/A converter clock cycles simplifies hardware and software system design while allowing for multichip synchronization. Additional features include:
- Integrated interpolation filters with selectable interpolation factors of 2, 4, and 8.
- A data interface supporting word and byte load, allowing customers to reduce input pins on lower data rates to save board space, power and cost.
