AN-1336 LMH0030 or LMH0031 Control Port Bussed Operation (Rev. B)
Texas InstrumentsIn systems using multiple LMH0030 serializer and LMH0031 deserializer devices it is often convenient to connect their ancillary data and control ports to a host controller using a bus network. This reduces the amount of wiring and PCB area required for this function. When designing such a network it is necessary to understand how the devices are controlled and used in a manner similar to micropr
Measuring Board Parasitics in High-Speed Analog Design
Texas InstrumentsSuccessful circuit designs using high-speed amplifiers can depend upon understanding and identifying parasitic PCB components. Simulating a design while including PCB parasitics can protect against unpleasant production surprises. This application report discusses an easy method for measuring parasitic components in a prototype or final PC board design by using a standard oscilloscope and low freq
MSP432 Platform Porting
Texas InstrumentsThe goals for this porting guide is to help developers accurately assess the effort to port an existing application from one MSP platform to another, ultimately to derive a porting strategy with compl

Usage of I2C for CDCE(L)949, CDCE(L)937, CDCE(L)925, CDCE(L)913
Texas InstrumentsThis document presents a method to smoothly change frequency by I²C? protocol on Texas Instruments CDCE(L)949, CDCE(L)937, CDCE(L)925, CDCE(L)913 Clock Synthesizers, thus avoiding unnecessary int
Filters for Data Transmission
Texas InstrumentsThe process of filtering an analog signal removes all frequencies above or below a corner frequency passing only a band of frequencies or rejecting a band of frequencies. When digital signals are filtered however a totally different set of constraints applies. This application note gives the designer a set of tools for implementing a filter that is the best compromise of interference rejecti
Interfacing the DAC8534EVM to TMS320C5x Processors
Texas InstrumentsThe DAC8534 is a quad-channel, low-power, 16-bit, serial digital-to-analog converter. This application report describes a method for interfacing the DAC8534 to the TMS320C5x-series DSKs using McBSP1 a
Get low-noise, low-ripple, high-PSRR power with the TPS717xx
Texas InstrumentsWhile highly efficient switching power supplies are commonly used for long battery life in portable end equipment such as mobile phones and PDAs, the internal circuitry of some of these devices is sensitive to noise and therefore does not operate properly when powered from a switching power supply with output ripple. Audio circuitry, PLLs, RF transceivers, and DACs are just a few examples of such circuits. Linear regulators are ideal for powering these circuits.
TMS320C55x Self-check Program: Version 1.0
Texas InstrumentsThe TMS320C55x?(C55x?) self-check program verifies the operation of DSP devices in the C55x generation 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 thor
LB-11 The LM110 - An Improved IC Voltage Follower
Texas InstrumentsThere are quite a few applications where op amps are used as voltage followers. These include sample and hold circuits and active filters as well as general purpose buffers for transducers or other high-impedance signal sources. The general usefullness of such an amplifier is particularly enhanced if it is both fast and has a low input bias current. High speed permits including the buffer in the signal path or within a feedback loop without significantly affecting response or stability. Low input current prevents loading of high impedance sources, which is the reason for using a buffer in the first place.
