Generation and Recognition of DTMF Signals With the Microcontroller MSP430
Texas InstrumentsThe first part of the Application Report describes the generation of DTMF signals using the Microcontroller MSP430. Following an explanation of the most important specifications which are involved, th
Seismic Sensor Demonstration Using an ADS1255 and TMS320VC5510A DSP (Rev. A)
Texas InstrumentsA prototype system for seismic sensing for such applications as oil exploration earthquake detection and acoustic monitoring is described. The system uses a delta-sigma converter and low-power DSP. Measured system performance met the requirements for such systems.
Optimizing JPEG on the TMS320C6211 2-Level Cache DSP
Texas InstrumentsThis application report describes the implementation and optimization techniques of the Joint Photographic Experts Group (JPEG) the still image compression standard on the TMS320C6211. The TMS320C6211 is a low-cost and high-performance digital signal processor (DSP) with 2-level caches that utilizes the VelociTI? very-long-instruction-word (VLIW) architecture.The TMS320C6211 has 64KB of L2 m
Bandsplitting Using Two GC2011 Digital Filter Chips
Texas InstrumentsThis application note describes how to use a single GC2011 chip to perform the real-to-complex down conversion operation on four signals simultaneously. The input data is split into even and odd samples and then multiplexed into a time division multiplexed (TDM) format. The even sample TDM stream is input to the A-input of the chip and the odd sample TDM stream is input to the B-input. The I-half

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

Texas InstrumentsDN119 -- Asynchronous Serial Mode for CC111xFx and CC251xFx
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.
Designing with the TPS54310 Synchronous Buck Regulator
Texas InstrumentsThe SWIFT TPS54310 externally compensated synchronous buck regulator makes designing a power solution quick and easy. The SWIFT Designer software tool is a resource that can greatly reduce design time by providing a complete power supply solution with only a few clicks of a mouse. The design methods presented in this application note are similar to the design methods used by the SWIFT Designe
