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.
Implementing an MPEG2 Video Decoder Based on the TMS320C80 MVP
Texas InstrumentsThis application report presents the preliminary results obtained in the realization of the MPEG2 video decoder on the Texas Instruments (TI(TM)) TM532OC80 MVP. We have addressed and solved the problems of bitstream scanning variable-length code decoding and inverse discrete cosine transform (DCT). The results obtained integrated with preliminary work and available information about time requir

TMS320C6410/13 Power Consumption Summary
Texas InstrumentsThis document discusses the power consumption of the Texas Instruments TMS320C6410™ and TMS320C6413™ digital signal processors (DSPs). Power consumption on C64x devices is highly application-dependent so a spreadsheet is provided to model power consumption for a user?s application. To get good results from the spreadsheet realistic usage parameters must be entered. The low-core volta
