KeyStone I-to-KeyStone II Migration Guide (Rev. A)
Texas InstrumentsThis guide describes the main System-on-Chip (SoC) level and peripheral changes that need to be considered when migrating a KeyStone I-based system design to a KeyStone II-based system design. <p> I
Synchronizing WiMAX Synthesizer TRF1x21/TRF1x12 to Arbitrary Reference
Texas InstrumentsTexas Instruments has a WIMAX RF chipset for base station and CPE applications that include integrated synthesizers to realize the superheterodyne architecture. For optimum channel resolution these devices must be tied to an 18-MHz reference frequency. In some systems the synthesizer reference frequency needs to be synchronized to a system reference frequency that may not be an integral multiple
General Application Setup for CDCR83/CDCFR83
Texas InstrumentsThis application note describes the Texas Instruments CDCR83 and CDCFR83 clocks for Direct Rambus system design. The document provides general guidance on power supply system board layout to achieve a high level of signal integrity and low clock jitter and translating switching level for various applications.

TMS320C6000 and TMS320C5000 McBSP Features Summary (Rev. A)
Texas InstrumentsThe multichannel buffered serial ports (McBSP) implemented on the Texas Instruments TMS320C6000™ and TMS320C5000™ digital signal processors (DSPs) are very similar. This document provides a summary of the McBSPs used in each of the C6000™ and C5000™ devices. It provides quick reference information on the specific McBSP features in each DSP. The full functional description o
Boost ISO120 Bandwidth to More Than 100kHz
Texas InstrumentsThere has been considerable demand for high-bandwidth isolation amplifiers. The highest bandwidth Burr-Brown ISO amps are the ISO100 and the ISO120/121/122 family with bandwidths of about 50kHz. The ISO120/121 bandwidth can be boosted to more than 100kHz by adding gain in the feedback.
Differences between Startup Timing for TMS470R1x Flash and ROM Controllers
Texas InstrumentsThis document describes the differences in the startup timing between flash and the ROM controller when using the same application software. The calculation of the difference in the startup timing behavior of a flash vs. a ROM controller is shown in an example. A method to minimize the startup behavior is described.

Synchronizing Three or More UCC28950 Phase-Shifted, Full-Bridge Controllers
Texas InstrumentsOne of the key features of the UCC28950 phase-shifted, full-bridge controller is its ability to synchronize its main oscillator to an external clock source. In this way, multiple controllers can be synchronized to improve performance criteria of the end power supply. This application report expands the details of the synchronization capability of the UCC28950, provides examples of simple circuits used to generate the proper clock inputs to the UCC28950, and gives examples of the input and output signaling that can be expected with three- and four-phase applications.
