The V.22 bis modem standard is a QAM type modem at 2400 bps implemented in full duplex. The V.22 bis modem implementation includes transmitter receiver with scrambling and V.14 as well as the handshake for connection in originate and answer mode. Modulation and demodu
TMS320DM357 Power Consumption Summary
Texas InstrumentsThis application report discusses the power consumption of the Texas Instruments TMS320DM357 digital media System-on-Chip (DMSoC). Power consumption on the DM357 device is highly application-dependent; therefore a spreadsheet that estimates power consumption is provided along with this document. To obtain good results from the spreadsheet realistic usage parameters must be entered (see Section 2

Using a TMS320C6000 McBSP for Data Packing (Rev. A)
Texas InstrumentsThis application report describes how to use the multichannel buffered serial port (McBSP) in the Texas Instruments TMS320C6000™ digital signal processor (DSP) for data packing. Data packing involves moving either multiple successive 8-bit elements to/from the McBSP as a single 16/24/32-bit element or multiple successive 16-bit words to/from the McBSP as a single 32-bit word.
The McBSP
AN-694 A DMOS 3A, 55V, H-Bridge: The LMD18200 (Rev. C)
Texas InstrumentsThis application note provides information on the LMD18200, which is optimized to work for applications that require 0.5A to 3.0A and operate from 12V to 55V.
Using CC2592 Front End with CC2530 (Rev. A)
Texas InstrumentsThis application report describes the pairing of the cost-effective SimpleLink™ ZigBee CC2530 wireless MCU with the SimpleLink CC2592 range extender to improve the receiver sensitivity and increase the total link budget enabling up to four times the range of each node in the ZigBee network. The combination of these devices creates a system solution that is ideal for applications such as hom
Guidelines for Using Decoupling Capacitors on DSP Designs
Texas InstrumentsThis document provides some guidelines for selecting decoupling capacitors for TMS320C3x devices.
Increasing UCC27221/2 Gate Drive Voltage
Texas InstrumentsThe UCC2722x contains an internal 6.5-V regulator from which the gate drive voltages for the high and low-side MOSFETs of a synchronous buck power stage are derived. In some instances it may be desirable to drive the MOSFET gates with a voltage other than 6.5 V. The output driver stage of the UCC2722x has an absolute maximum voltage rating of 10 V. However it is still possible to bypass the inter
How to Begin Development Today & Migrate Across the TMS320C6202/02B/03B/04 DSPs (Rev. D)
Texas InstrumentsDevelopment can begin now for Texas Instruments TMS320C6202, C6202B, C6203B, and C6204 digital signal processor (DSP) systems.
Because of the compatibility between TMS320C6000™ generation devices, existing C6000™ tools and development platforms can be used to develop code for the current TMS320C62x™ generation and other future devices. This capability allows systems to be up and running when silicon becomes available.
This document briefly describes the similarities and differences between the C6202/02B/03B/04 digital signal processors (DSPs), and serves as a reference for designers migrating between the C6202/02B/03B/04, either for performance improvement, or improved feature set.

Multipass Linking
Texas InstrumentsLarge projects are frequently broken down into subsystem teams each of which develops their portion of the application independently of the others. In order to create a final executable all the modules from all the subsystem teams need to be combined. One way to do this is to have each subsystem team supply a linked relocatable file to the system integrator. The system integrator would then link
UCC28070 Implement Bridgeless PFC Pre-Regulator Design
Texas InstrumentsBridgeless power factor correction (PFC) topology is attracting attention as a means of satisfying the new high-efficiency requirements. This application report reviews the UCC28070 and its design considerations for bridgeless PFC. It present a bridgeless solution that is relatively easy to implement in that it does not require any additional circuitry for current sensing and that the operation re
Symmetric PWM Outputs Generation with the TMS320C14 DSP
Texas InstrumentsPulse Width Modulated (PWM) signal generation is crucial to many motor and motion control applications. PWM signals are pulse trains with fixed frequency and magnitude and variable pulse width. There is one pulse of fixed magnitude in every PWM period. However the width of the pulses changes from period to period according to a modulating signal. This document discusses how to generate symmetric
