Calculation Of TMS320C5x Power Dissipation
Texas InstrumentsThe power supply current requirements for the 16-bit fixed-point TMS320C5x digital signal processor (DSP) depend not only on the device functionality but also on the system parameters. This document describes the techniques for analyzing the system and device operating current levels. Once these factors are determined the power dissipation can be calculated followed in turn by the device thermal
SPI Slave Transmit Timing
Texas InstrumentsSeveral versions of the SPI on TI TMS470 devices transmit on the receive edge of the SPI clock (SPCLK) in slave mode (SOMI). This functionality was added as an enhancement to increase the speed of SPI transfers.
Because of the design implementation the SOMI signal is generated with enough setup and hold time relative to the SPI clock to guarantee correct data transfer at the speeds used on devi
Designing a Split-Rail SEPIC With the TPS61175
Texas InstrumentsOften a regulated DC output voltage is needed between the minimum and maximum input voltages of a DC/DC converter but neither a buck or boost converter in standard configurations is sufficient. However a boost converter integrated circuit (IC) can be configured to drive a single-ended primary inductor converter (SEPIC) power stage and provide an output voltage that is between the input voltage
Comparison And Selecting of PC Card Power Controllers
Texas InstrumentsWith so many PC Card power controller options available from Texas Instruments it may be somewhat difficult for designers to select a particular device. This report summarizes all of the similarities and differences such as features and options between all of these PC Card power controllers to help eliminate any potential confusion. With the help of this report the designer can select an exact
Porting A SPOX-KNL V2.2 Application to DSP/BIOS II
Texas InstrumentsDSP/BIOS II supports a single set of programming APIs for both BIOS and SPOX?KNL that is as scalable as possible. In cases where similar APIs exist in both BIOS and SPOX the BIOS APIs are used. This may present some incompatibilities between the current BIOS kernel APIs and their counterparts in SPOX v2.2. This document describes the major incompatibilities and provides instructions for porting a
CDCE72010 as a Clocking Solution for High-Speed Analog-to-Digital Converters
Texas InstrumentsTexas Instruments has recently introduced a family of devices suitable to meet the demands of high-speed high-IF sampling analog-to-digital converters (ADCs) such as the ADS5483 which is capable of sampling up to 135 MSPS. To realize the full potential of these high-performance devices the system must provide an extremely low phase noise clock source. The CDCE72010 clock synthesizer chip offers

UCC28700 5-W USB Flyback Design Review (Rev. C)
Texas InstrumentsIn USB and isolated low power converter designs quasi resonant and discontinuous conduction mode flyback converter topologies are a popular choice due to their low parts count and relatively low cost. To reduce the cost even further in these designs TI has developed a quasi-resonant/discontinues current mode flyback controller with primary side control.
