The AD9856AST from Analog Devices is a high-speed Quadrature Digital Upconverter (QDUC) IC. It integrates a direct digital synthesizer (DDS), a 12-bit digital-to-analog converter (DAC), clock multiplier circuitry, and digital filters onto a single chip.
This device is suitable for communications applications where cost, size, power, and dynamic performance are critical. It offers a DC to 80 MHz output bandwidth and features like programmable sample rate interpolation filters and a programmable reference clock multiplier. The SFDR performance is rated at >52 dB @ 40 MHz AOUT and >48 dB @ 70 MHz AOUT.
The AD9856AST operates on a single +3 V supply and comes in a space-saving 48-LQFP surface-mount package. It is specified for an extended industrial temperature range of -40°C to +85°C.
Applications include HFC data, telephony, and video modems, wireless and satellite communications, and cellular base stations.
