The AD9850 is a highly integrated device that uses advanced DDS technology coupled with an internal high speed, high performance, D/A converter and comparator, to form a complete digitally programmable frequency synthesizer and clock generator function. When referenced to an accurate clock source, the AD9850 generates a spectrally pure, frequency/ phase-programmable, analog output sine wave. This sine wave can be used directly as a frequency source or converted to a square wave for agile-clock generator applications. The AD9850’s innovative high speed DDS core provides a 32-bit frequency tuning word, which results in an output tuning resolution of 0.0291 Hz, for a 125 MHz reference clock input. The AD9850’s circuit architecture allows the generation of output frequencies of up to one-half the reference clock frequency (or 62.5 MHz), and the output frequency can be digitally changed (asynchronously) at a rate of up to 23 million new frequencies per second. The device also provides five bits of digitally controlled phase modulation, which enables phase shifting of its output in increments of 180°, 90°, 45°, 22.5°, 11.25° and any combination thereof. The AD9850 also contains a high speed comparator that can be configured to accept the (externally) filtered output of the DAC to generate a low jitter square wave output. This facilitates the device’s use as an agile clock generator function.The frequency tuning, control, and phase modulation words are loaded into the AD9850 via a parallel byte or serial loading format. The parallel load format consists of five iterative loads of an 8-bit control word (byte). The first byte controls phase modulation, power-down enable, and loading format; bytes 2–5 comprise the 32-bit frequency tuning word. Serial loading is accomplished via a 40-bit serial data stream on a single pin. The AD9850 Complete-DDS uses advanced CMOS technology to provide this breakthrough level of functionality and performance on just 155 mW of power dissipation (+3.3 V supply).The AD9850 is available in a space saving 28-lead SSOP, surface mount package. It is specified to operate over the extended industrial temperature range of –40°C to +85°C

The ADG411, ADG412, and ADG413 are monolithic CMOS devices comprising four independently selectable switches. They are designed on an enhanced LC2MOS process which provides low power dissipation yet gives high switching speed and low on resistance.The on resistance profile is very flat over the full analog input range ensuring excellent linearity and low distortion when switching audio signals. Fast switching speed coupled with high signal bandwidth also make the parts suitable for video signal switching. CMOS construction ensures ultralow power dissipation, making the parts ideally suited for portable and battery-powered instruments.The ADG411, ADG412, and ADG413 contain four independent SPST switches. The ADG411 and ADG412 differ only in that the digital control logic is inverted. The ADG411 switches are turned on with a logic low on the appropriate control input, while a logic high is required for the ADG412. The ADG413 has two switches with digital control logic similar to that of the ADG411 while the logic is inverted on the other two switches.Each switch conducts equally well in both directions when on, and each has an input signal range that extends to the supplies. In the off condition, signal levels up to the supplies are blocked. All switches exhibit break-before-make switching action for use in multiplexer applications. Inherent in the design is low charge injection for minimum transients when switching the digital inputs.PRODUCT HIGHLIGHTS Extended signal range The ADG411, ADG412, and ADG413 are fabricated on an enhanced LC2MOS, giving an increased signal range which extends fully to the supply rails. Ultralow power dissipation. Low RON Break-before-make switching This prevents channel shorting when the switches are configured as a multiplexer. Single-supply operation For applications where the analog signal is unipolar, the ADG411, ADG412, and ADG413 can be operated from a single-rail power supply. The parts are fully specified with a single 12 V power supply and remain functional with single supplies as low as 5 V.APPLICATIONS Audio and video switching Automatic test equipment Precision data acquisition Battery-powered systems Sample-and-hold systems Communication systems

The ADSP-21160N SHARC® DSP is the second iteration of the ADSP-21160. Built in a 0.18 micron CMOS process, it offers higher performance and lower power consumption than its predecessor, the ADSP-21160M. Easing portability, the ADSP-21160N is application source code compatible with first generation ADSP-2106x SHARC DSPs in SISD (Single Instruction, Single Data) mode. To take advantage of the processor’s SIMD (Single Instruction, Multiple Data) capability, some code changes are needed. Like other SHARCs, the ADSP-21160N is a 32-bit processor that is optimized for high performance DSP applications. The ADSP-21160N includes a 100 MHz core, a dual-ported on-chip SRAM, an integrated I/O processor with multiprocessing support, and multiple internal buses to eliminate I/O bottlenecks.The ADSP-21160N introduces Single-Instruction, Multiple-Data (SIMD) processing. Using two computational units (ADSP-2106x SHARC DSPs have one), the ADSP-21160N can double performance versus the ADSP-2106x on a range of DSP algorithms.The ADSP-21160N continues SHARC’s industry-leading standards of integration for DSPs, combining a high-performance 32-bit DSP core with integrated, on-chip system features. These features include a 4M-bit dual ported SRAM memory, host processor interface, I/O processor that supports 14 DMA channels, two serial ports, six link ports, external parallel bus, and glueless multiprocessing.

The ADSP-21161 SHARC® DSP is the newest member of the Super Harvard Architecture (SHARC) family of programmable DSPs. Capable of 600 million math operations per second (MFLOPs), the ADSP-21161 sets a new level of performance for low-cost SHARC DSPs - more than three times the performance for comparable models at about the same price. Its road map includes a cost-effective path to 1200 MFLOPS for $5 per unit and a performance-driven path to 10 GFLOPS and beyond.'This newest edition to the SHARC family will open more possibilities for designers to design-in high performance digital signal processing into client-side applications and should help others reconsider applications they couldn’t do before with a single chip,' said Will Strauss, president of Forward Concepts. 'Analog Devices will certainly maintain customer loyalty with this road map.' The ADSP-21161 DSP is the second member of the SHARC DSP family of 32-bit floating-point programmable DSPs to be based on a SIMD core architecture that is optimized for digital signal processing performance. Like all SHARCs, the ADSP-21161 is code-compatible with all other members of the family and supports both fixed- and floating-point data types. The ADSP-21161 lowers the price for SIMD SHARC DSP performance and is an outstanding DSP solution for many price-sensitive applications.State-of-the-Art Development Tools The ADSP-21161, like all SHARC processors, is supported by a complete set of software and hardware development tools. The VisualDSP++® tool set offered by Analog Devices includes an optimizing C/C++ compiler, integrated development environment (IDE), assembler, linker, splitter and cycle accurate simulator that support both C and assembly debugging. Emulation support is JTAG-based and ADI offers USB, PCI, and Ethernet based emulators. SHARC DSP Roadmap There are two code-compatible paths that the SHARC DSP roadmap will follow. One optimized for high-performance multiprocessing systems and the other for price/performance. Performance is the key for multiprocessing applications and this is the reason that ADI will offer 10 GFLOP SHARC DSPs in the future. On-chip memory sizes will be balanced to match this performance with memories increasing to unprecedented levels (64 Mbit) using newly developed technologies.Industry leading price/performance will be the driver on the other path of the roadmap. In the future, these SHARC DSPs will offer an increase in performance to 1200 MFLOPs while decreasing price to as low as $5.00. This is required to support new technologies that demand substantial signal processing performance at consumer price points.
