Clock Speed Doubled for DDS ICs
Analog Devices Inc. announces that it has more than doubled the clock speed of direct digital synthesizer (DDS) integrated circuits (ICs) with on-chip 14-bit digital-to-analog converters (DACs). The AD9910 and AD9957 achieve speeds of 1 G samples per second (GSPS), while lowering power consumption by more than 50%, ensuring the DDS ICs meet the requirements of a broad range of communications, instrumentation and defense applications. The 1 GSPS operating speed combined with the 14-bit DAC resolution of the AD9910 DDS allows communications, defense and instrumentation system engineers to improve dynamic performance for output frequencies to 400 MHz. For wireless and wired systems, the AD9957 DDS modulator or quadrature digital upconverter (QDUC) simplifies data transmission by offering real outputs up to intermediate frequencies of 400 MHz.
