I2C Communication over DS90UB913/4 FPD Link-III with BCC
Texas InstrumentsThis application note describes I2C communication between DS90UB913/914 devices through the FPDLinkIII bidirectional control channel (referred as BCC). The low latency BCC interface allows the masterI2C device to remotely communicate with peripherals across the serial link.
AN-1082 Adjust or Synchronize LM2586/88 Switching Frequency (Rev. B)
Texas InstrumentsSwitching frequency is a very important parameter in switching power converters. As the switchingfrequency increases the physical size of magnetic elements and other components in the circuit reducesignificantly. Switching frequency also plays a great role in control loop gain and compensation design.Switching frequency determines the maximum allowable bandwidth of the control loop. Switchi

Optimizing LMX243x Input Sens Using Simple Matching Techniques (Rev. A)
Texas InstrumentsThe following application report describes how maximum power can be delivered from the voltage controlled oscillator (VCO) output to the FinRF input of a LMX243x frequency synthesizer by means of performing a single element match.
Using the DCO Library (Rev. A)
Texas InstrumentsThis document serves as an overview describing the use of the DCO library within existing C or assembly projects. This library encapsulates routines used for setting the DCO to a specific speed based on a multiplication of a known clock such as a 32-kHz crystal. These functions are written in assembly to be optimized for the MSP430 but can be called from any C program that includes their header f
