Analog Devices AD9858 Manuals

The AD9858 is a high performance, 1GSPS direct digital synthesizer.

The AD9858 is a direct digital synthesizer (DDS) featuring a 10-bit DAC output. It has an internal clock speed of 1 GSPS and supports up to a 2 GHz input clock (selectable divide-by-2). The device integrates a 10-bit D/A converter and has a phase noise of less than 145 dBc/Hz @ 1 kHz offset. The output frequency is 100 MHz (DAC output) and it has a 32-bit programmable frequency register. It supports a simplified 8-bit parallel and SPI serial control interface and has automatic frequency sweeping capability. The device operates on a 3.3 V power supply with a typical power dissipation of 2 W. It also integrates a programmable charge pump and phase frequency detector with a fast lock circuit. The charge pump supply can be isolated up to 5 V. Additionally, the AD9858 integrates a 2 GHz mixer.

AD9858 is a 1GSPS direct digital synthesizer (DDS) with a built-in 10-bit D/A converter, supports automatic frequency sweeping, and is used in VHF/UHF LO synthesis, tuners, instrumentation, agile clock synthesis, cellular base station hopping synthesizers, radar, and Sonet/SDH clock synthesis.

The AD9858 is a direct digital synthesizer (DDS) that generates frequencies up to 1GSPS. It integrates a 10-bit DAC, a 32-bit programmable frequency register, a simplified 8-bit parallel and SPI® serial control interface. The AD9858 also features automatic frequency sweeping capability, making it suitable for frequency synthesis applications such as VHF/UHF LO synthesis, tuners, instrumentation, agile clock synthesis, cellular base station hopping synthesizers, radar, and Sonet/SDH clock synthesis.
