IEEE 1588 Synchronization Over Standard Networks Using the DP83640 (Rev. A)
Texas InstrumentsThis application report describes a method of synchronization that provides much more accuratesynchronization in systems with larger PDV. The method described attempts to detect minimum delays or'lucky packets'. The method also takes advantage of the DP83640 clock control mechanism to separatelycontrol clock rate and time corrections minimizing overshoot or wild swings in the accuracy of t
Understanding the Davinci Resizer (Rev. B)
Texas InstrumentsThe image-scaling operation is one of the most commonly used video and imaging processing functions. The resizer hardware module in the DaVinci™ video processing subsystem (VPSS) provides the scaling capability in hardware therefore off-loading the system for other processing tasks. To achieve good video quality while maintaining good overall system performance a better understanding of th

High Speed Clock Distribution Design Techniques for CDC 509/516/2509/2510/2516 (Rev. A)
Texas InstrumentsThe memory bandwidth of high performance microprocessors is increasing at a rapid rate and the future memory bandwidth requirements are expected to keep increasing. The bandwidth requirements of RAM will be satisfied in the near term by using Synchronous DRAM. The need to drive multiple DRAM chips at high speeds with low skew necessitates the use of clock distribution devices with Phase Locked Loo
Extended-Precision Complex Radix-2 FFT/IFFT Implemented on TMS320C62x (Rev. A)
Texas InstrumentsThe limited dynamic range of a fixed-point DSP causes accuracy problems in Fast Fourier Transform (FFT) calculation. This is due to quantization and the scaling that has to be applied to prevent output overflow. Hence there is a need to perform the calculations in extended precision especially for large FFT sizes. Highly optimized extended-precision assembly routines for the FFT and its inverse
U-165 Design Rvw: Isolated 50 W Flyback Converter Using UCC3809 and UC3965
Texas InstrumentsThe flyback power stage is a popular choice for single and multiple output DC-to-DC converters at power levels of 150W or less. Without the output inductor required in buck-derived topologies such as the forward or push-pull converter the component count and cost are reduced. This application note will re-view the design procedure for the power stage and control electronics of a flyback converte

AN-1852 Designing With pH Electrodes (Rev. A)
Texas InstrumentsA pH electrode measures hydrogen ion (H+) activity and produces an electrical potential or voltage. Theoperation of the pH electrode is based on the principle that an electric potential develops when two liquidsof different pH come into contact at opposite sides of a thin glass membrane. This was originallydiscovered in 1906 by Max Cremer [1]. His discovery laid the foundation for Fritz Habe
