DN610 -- Design Notes

U.S digital cellular terminal designs commonly use programmable digital signal processors (DSPs). All digital cellular transmitters employ conventional and CRC codes to protect against channel-induced errors. Receivers use Viterbi decoders and CRC syndrome checks to verify that the decoded data contains no errors. This document presents examples of error-protection and correction functions for VSE

Precise Tri-Wave Generation

Despite the fact that the UC3842 and the UCC3802 PWM Controllers are pin-for-pin compatible, they are not drop-in replacements for each other. Designed as the next generation '42, the UCC3809 also has

TVP5146 Anti-Aliasing Filters

This reference design is intended for designers who wish to design up to eight TMS320C6472 Digital Signal Processors into a system using a nominal input voltage of 5 V, with a flexible design using ex

This document describes considerations for migration from Texas Instruments TMS320DM6446 Digital Media System-on-Chip (DMSoC) to the TMS320DM6467 DMSoC. Both devices feature a dual-core architecture u

The TAS3001C stereo audio digital equalizer provides a serial control interface using the I2C protocol. Since the TAS3001C is more complex than the typical serial EEPROM often found on an I2C bus designers must consider additional aspects of the I2C specification. Methods of interfacing to the TAS3001C applicable to a wide variety of I2C masters are discussed.

SPACE-VECTOR PWM WITH TMS320C24X USING HARDWARE AND SOFTWARE DETERMINED SWITCHING PATTERNS

This application report describes a smart-battery charger reference design with a wide-input-voltage range. The reference design implements the System Management Bus (SMBus) protocol for communication

This application report describes how to configure the time-division multiplexing mode in TLV320AIC3x codec devices and discusses the associated protocol timing diagram for the I2C and DSP modes of operation with various offset programmability. This document also explains how to interface and communicate multiple TLV320AIC3x devices using single audio data interface with the host/multimedia proces

Application Note 556 Introduction to Power Supplies

The UCC3750 Source-Ringer Controller provides a complete control and drive solution for a four quadrant flyback-based ring generator circuit. The IC controls a primary-side switch which is modulated when power transfer is taking place from input to output. It also controls two secondary switches which act as synchronous rectifier switches during positive power flow. These switches are pulse-widt

TPS3700 Using the TPS3700 as a Negative Rail Over- and Undervoltage Detector

TVP5150AM1 Patch Code Download Guidelines

TMS470 microcontroller devices built using the F05 flash process have a built-in mechanism for detecting weak or degraded flash bits before they fail. A way of using this mechanism is discussed in this application report.

Digital visual interface (DVI) may be thought of as a plug in card interface with significant size and complexity. It can however, be easy to implement DVI on a motherboard using the Intel 865G chipse

Driving High-Speed Signals in Data Center Servers and Storage Area Networks

This program is designed to verify the operation of DSP devices in the TMS320C62x? DSP family by checking for proper operation of the CPU core and internal RAM. On-chip peripherals are not tested since doing so would be target system dependent. It is important to note that this program only provides a confidence check. It is not as comprehensive as the tests done at production which thoroughly ch
