Continuous Monitor of the PLL Frequency With the DCC
Texas InstrumentsThe Dual Clock Compare (DCC) may be configured to provide autonomous real-time monitoring of the average frequency of a signal. This application report illustrates a configuration in which the DCC monitors the average PLL frequency. This comparison triggers an error when the average PLL falls out of a specified range. The accuracy window and the duration over which the frequency is averaged must

A DSP/BIOS AIC23 Codec Device Driver for the TMS320DM642 EVM
Texas InstrumentsThis document describes the usage and design of a device driver for the AIC23 audio codec on the TMS320DM642 EVM. This device driver is written in conformance to the DSP/BIOS™ IOM device driver model and uses the generic TMS320C6x1x EDMA McASP driver to transfer samples to and from the serial port. For details on this generic driver see the application note A DSP/BIOS EDMA McASP Device D
LO Harmonic Effects on TRF3705 Sideband Suppression
Texas InstrumentsThe LO harmonic effects on I/Q errors and sideband suppression (SBS) in the RF modulator was analyzed in application report SLWA059. This application report further investigated LO harmonic effects when attempting to achieve an increased level of SBS performance. The selectivity requirements for the second- and third-order harmonics are outlined to aid in proper filter design. In the measurement

Texas InstrumentsThis Application Note describes a method of interfacing a given microcontroller with a Texas Instruments digital temperature sensor.
Building a Superior Battery Monitor with the bq27x00
Texas InstrumentsThe bq27x00 is a complete gas gauge solution for lithium-ion and lithium-polymer batteries. The bq27x00 also has internal registers and control commands that enable the host to use it as a battery monitor. A battery gas gauge solution can be built one of two ways: ignore all algorithms built into the bq27x00 and use the primitive functions to build a fully customized solution or use some of the h
TFT-LCD Power Supply Using TPS65120 Single Inductor Quadruple-Output Powr Supply

TMS320C6201 (Revision 2.x) to TMS320C6201B (Revision 3.X) (Rev. A)
Texas InstrumentsSamples of the Texas Instruments (TI™) TMS320C6201B DSP will be available in the second half of 1998 with volume production starting at the end of the year. The TMS320C6201B revision is manufactured using a 0.18-micron process compared to the currently available revision 2 that uses a 0.25-micron process. The use of a smaller process for the TMS320C6201B DSP will lead to significantly lower
