This application report contains implementation instructions for the DDR2 interface contained on the TMS320DM644x digital signal processor (DSP) device. The approach to specifying interface timing for

Designing Non-Inverting Buck-Boost (Zeta) Converters with a Buck P-FET Controller

Healthcare and medical research has seen increased usage of medical images in recent years. This usage often involves visualization of three-dimensional (3D) data sets as well as accurately relating information in different images for diagnosis treatment and basic science. Image registration and volume rendering operations often involve some combination of rotation scaling shifting and shearing

This application note discusses the uses of the LM339 quad comparator and the LM324 op amp areamong the most widely used linear ICs today. The combination of low cost single or dual supply operationand ease of use has contributed to the wide range of applications for these devices.

Difficulty receiving messages on phases B and D of the FLEXTM signal while successfully receiving messages on Phases A and C usually indicates the receiver audio output is not properly interfaced to the TLV5590. The FLEX chipset requires proper consideration of the TLV5590 input interface to insure the correct digital conversion of the demodulated 4 Level FSK (Frequency Shift Keying) audio output

The DSP101 and DSP102 sampling analog-to-digital converters have all the interface logic to connect directly to popular digital signal processor ICs from ADI AT&T Motorola and Texas Instruments. A unique tag input allows additional serial data to be appended to the serial data stream that is sent to the DSP processor. When the DSP101 is coupled with an analog multiplexer this tag feature can

Fiber optic transmission is assuming an increasingly important role in systems for wide-band analog signals and digital signals with high data rates. Although the number of applications for digital networks and telecommunications systems is skyrocketing analog transmission is still vital to many applications. Analog systems with bandwidths of up to 150MHz are used for wide-band RGB signal distrib

This design note describes ways to drive an optocoupler. One of the most popular is to use a TL431 Adjustable-Shunt Regulator. However a regulator-control lC-such as the UC3832 UC3833 or UC3836 substituted for the TL43431-provides numerous additional features besides regulating the output. Overcurrent limiting and fault-protection handshaking with external control logic and the introduction of

The UCC28251 is a functional variant of the UCC28250 PWM Controller. While the same basic functionality of the UCC28250 is largely maintained the UCC28251 is designed to operate at a lower frequency (minimum of 27 kHz when programmed by RT pin) allowing operation in 400-V input DC-to-DC converters in off-line AC-to-DC power supplies where frequency-dependent high-voltage switching lossesare an

The Power Drive Protection Interrupt (PDPINT) pin is a safety feature that is built into all TMS320C24? DSPs. This feature protects the electrical drive from damage due to any electrical, mechanical o

FRAM is a non-volatile memory technology that behaves similar to SRAM while enabling a whole host of new applications, but also changing the way firmware should be designed. This application report ou

Sine-wave generators are fundamental building blocks of signal processing systems for use in control applications. This application note describes two different methods for implementing a digital Sine wave generator using the TMS320C2xx. The first method is a fast direct table look-up with linear interpolation to provide Sine waves with a minimum harmonic distortion. The second method realizes th

This application report provides information about the process to upgrade an existing 10/100 Mb/sEthernet design using Intel’s LXT972M Ethernet Physical Layer (PHY) product our new DP83848C/I/YBPHYTER product.

This application report describes how to communicate with the Hercules™ serial peripheral interface (SPI) bootloader. The SPI bootloader is a small piece of code that can be programmed at the beginning of Flash to act as an application loader as well as an update mechanism for applications running on a Hercules Cortex™-R4 based TMS570LS04x microcontroller.
