A low-side, current-sensing resistor in a fast-charge control circuit generates a small voltage drop between the low side of the battery pack and ground. This drop is not a problem in most cases; howe
This application report explains a technique that uses two MSP430™ microcontrollers to expand the maximum number of LCD segments that can be driven with a single controller. Additional benefits of the technique include increases in available memory data storage (RAM) and I/O control lines. These benefits are realized without the need for an external LCD driver circuit. The use of a second
The development of realistic predictions to assist the power supply engineer during the control loop design process is facilitated in this application report by appropriate small-signal and bode plot analysis the validity of which is verified through simulation results.
Sources of noise generation are pervasive in contemporary industrial applications. Unwanted noise presents one of the major problems in measuring power or protecting circuits in such an environment. Knowing the characteristics and understanding the behavior of noise sources are valuable to designers and users of electronic circuits. The first part of this report defines some fundamental concepts o
The dual-band handset market is expanding very rapidly due to the increase in customers requiring roaming capability. The customer also demands that handsets have an increase in features while keeping
Samples 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
This application report is a general guide for using the CDC7005 clock synchronizer/synthesizer and jitter cleaner from Texas Instruments. This report explains the basic functionality and methods for using the device efficiently along with the results of evaluations. It also describes the clock termination method decoupling the power supply and general applications.
JPEG compression/decompression technique is widely used for still image applications. There are two major ways to implement JPEG algorithm--hardware and software. The hardware approach is good for spe
Cost and performance requirements continue to push the packaging of electronic systems into smaller and smaller spaces. The advent of surface-mount devices has brought pin spacings that differ from on
As intermediate bus voltages decrease, a corresponding increase in line card load currents further complicates the design of power distribution and control sub-systems in networking equipment. As one
This document describes how to link together the GSM full-rate (FR) half-rate (HR) enhanced full-rate (EFR) and adaptive multi-rate (AMR) voice coding implementations on the TMS320C62x(tm) digital signal processor (DSP).
This document helps designers use existing clock-driver products to drive large loads while maintaining a minimum amount of skew between the device outputs. The emphasis of this document is using parallel or ganged outputs to drive loads. A performance evaluation of the CDC201 is provided.
