Reading and Understanding an ESD Protection Datasheet
Texas Instruments<p>System engineers must choose all components for their designs carefully. Picking the right ESD protection elements can be challenging as the matter of protecting devices on the PCB against ESD str
AN-1412 Micro SMDxt Wafer Level Chip Scale Package (Rev. K)
Texas InstrumentsMicro SMDxt is a wafer level CSP (WLCSP) with the following features:
- Package size equal to die size
- Smallest footprint per I/O count
- No need for underfill material
- Interconnect layout available in 0.4 mm or 0.5 mm pitch
- No interposer between the silicon IC and the printed circuit board
Audio Echo on the DM642 EVM
Texas InstrumentsThe software demonstrates an audio loopback example on the DM642 EVM with programmable echo added to the input signal. The demonstration creates and primes the audio I/O streams initializes the echo buffer enters a loop reading audio samples then processes the samples and writes them back into the audio codec.
The demonstration:
- Computes the read pointer and adds a sample on each
System Testability Using Standard Logic (Rev. A)
Texas InstrumentsThe use of more sophisticated ASICs and microprocessors and a steadily increasing move toward surface-mount packaging has led to the increasing complexity and density of digital systems. These advances improve system performance and decrease the physical size of printed-circuit boards (PCBs) but complicate the task of system testing. Access to test nodes using bed-of-nails testing is red

DN507 -- FEC Decoding
Texas InstrumentsThe purpose of this design note is to show how the FEC decoding implemented in HW on the CC1100 CC1100E CC1101 CC1110Fx CC1111Fx CC1150 CC2500 CC2510Fx CC2511Fx and CC2550 can be implemented in SW. This is in particular very important for the CC430Fx device which has the same radio as the CC1101 and CC1110/11Fx but without HW FEC included.

Online Stack Overflow Detection on the TMS320C28x DSP
Texas InstrumentsA stack overflow in an embedded DSP application generally produces a catastrophic software crash due to data corruption lost return addresses or both. Traditional off-line approaches to sizing a stack during development such as filling with a know value or estimating based on code content are not 100% reliable. Therefore programmers often feel compelled to reserve larger stack sizes than are
Understanding and Enhancing Sensitivity in Receivers for Wireless Applications
Texas InstrumentsThis technical brief provides an overview of communication receiver sensitivity. One of the most important parameters in determining the overall performance of a communication system, receiver sensiti
The DDC112's Test Mode
Texas InstrumentsThis application bulletin covers the DDC112’s test mode. It elaborates on the explanation given in the data sheet and is written with the purpose of helping you use the test mode to its fullest capability. It does assume a basic understanding of the DDC112’s operation. For a good introduction to the DDC112, see the DDC112’s data sheet.
The organization of this application bulletin is as follows: First, an overview presents the basic operation of the test mode. Next are explanations of single packet and multiple packet test signals. Noise and linearity performance of the test mode are then covered followed by some special considerations for using the test mode. Finally, a program for investigating test mode performance is discussed with the listing for the program given afterwards.
Designing Switching Voltage Regulators with TL497A
Texas InstrumentsSwitching voltage regulators represented by the TL497 can achieve high-efficiency power conversion at large input/output voltage differentials. The TL497A eliminates complex circuit designs previously required and provides greater efficiency than systems using series pass regulators. The principle of operation is discussed and practical design exercises for step-down step-up and inverting reg
Viterbi Decoding Techniques for the TMS320C55x DSP Generation (Rev. A)
Texas InstrumentsIn most wireless communications systems convolutional coding is the preferred method of error-correction coding to overcome transmission distortions. This report outlines the theory of convolutional coding and decoding and explains the programming techniques for Viterbi decoding in the Texas Instruments TMS320C55x™ generation of digital signal processors (DSPs). The same basic methods deco
