Predator: A Posture Tracking System
Texas InstrumentsThe fields of telepresence and virtual reality have experienced a surge of activity in recent years. The goal of these fields is to place users in an immersive environment that behaves like the real world. To achieve this goal fields require the use of next-generation input devices such as data gloves head-mounted displays and various other immersive peripherals. Posture capture and recognition
Quick Start Guide to the Smart Meter Reference Design
Texas InstrumentsThe smart meter reference design from Texas Instruments is a comprehensive tool that demonstrates the capabilities of a smart meter. The smart meter board (SMB) performs energy or electricity metering and has the capability of transferring key meter data via wired and wireless sensors to form a simple automatic meter reading (AMR) system. This is a quick start guide to reference design SMB 2.5. Th

Using the LMK0480x/LMK04906 for Hitless Switching and Holdover
Texas InstrumentsThis application report discusses some of the key performance results when using LMK0480x/LMK04906to implement hitless switching between reference clocks. Hitless Switching is required in certainapplications such as SONET/SDH/line port cards and routers/switchers in order to minimize thepropagation of phase transients to the clock outputs during reference clock switching. On loss of all vali
UCC28950 600W Phase Shifted Full Bridge Design Review/Application Report (Rev. C)
Texas InstrumentsIn high-power server applications to meet high-efficiency and green standards some power-supply designers have found it easier to use a phase-shifted, full-bridge converter. This is because the phase-
Power Supply Design for the ADS41xx (Rev. A)
Texas InstrumentsSystem designers traditionally power the high-speed data converter in their systems from a low-noise low-dropout linear regulator (LDO) in order to achieve the performance described in the analog-to-digital converter (ADC) data sheet. However LDOs inherently are not very power efficient. Switching regulators on the other hand offer good power efficiency but typically come with higher output no
Understanding Serial LVDS Capture in High-Speed ADCs
Texas InstrumentsThis application note describes various schemes of interfacing serialized low-voltage differential signaling (LVDS) data outputs from high-speed analog-to-digital converters (ADCs) to a field-programmable gate arrays (FPGAs) or other application-specific integrated circuit (ASIC)-based receivers. This note provides an introduction to standard one-wire interfaces and other interface variants (such
Implementing a CDC7005 Low Jitter Clock Solution for HIgh Speed High IF ADC Dev
Texas InstrumentsTexas Instruments has introduced a family of devices suited to meet the demand for high-speed high-IF sampling ADC devices like the ADS5500 ADC capable of sampling at 125 MSPS. To realize the full potential of these high performance devices it is imperative to provide an extremely low phase noise clock source. The CDC7005 clock distribution chip offers a real-world clocking solution to meet the
AN100 - Crystal Selection Guide (Rev. C)
Texas InstrumentsRF systems are highly dependent on accurate clocks for correct operation. A deviation in clock frequency is directly reflected as a deviation in radio frequency. This can degrade RF performance violate legal requirements or in worst case lead to a non-functioning system.
The scope of this application report is to give the design engineer a quick guide on how to design tune and verify the

Memory Transfers With TMS320VC5420 and TMS320VC5421 DSPs
Texas InstrumentsThe TMS320VC5420 and TMS320VC5421 dual CPU DSPs feature two 6-channel DMA Controllers (DMAC) plus Host Port Interface Controllers (HPI) for efficient movement of data without involvement of the CPUs.Internal transfers can move data between the two DSP subsystems or within each subsystem. Typical internal transfers read and write data between on-chip memories and peripherals. Memory transfers

Selecting High-Speed Operational Amplifiers Made Easy (Rev. A)
Texas InstrumentsHigh-speed op amps come in current- and voltage-feedback versions. Voltage-feedback amplifiers are sometimes de-compensated to allow greater speed. This technique has been superceded by current-feedback amplifiers. Differential-output op amps are gaining popularity for transformerless A/D interfaces.
