Designing robust, fault-tolerant motion control feedback systems

This article reviews basic servo systems and development of the fault-tolerant feedback systems for servo systems. Controller receiver circuit design, proper PC-board receiver circuit layout, and the encoder's signal cable and termination are discussed. Additionally, various types of industrial feedback encoders are presented, along with the various types of faults that can develop in a servo feedback system.

Choosing the Right 1-Wire Host for Your Embedded Application

This application note presents four categories of 1-Wire master circuits for embedded applications and discusses their capabilities and requirements in relation to available (ie, unused) system resources. The schematics shown here apply to short networks that do not extend beyond the radius of 1 meter and are populated with a small number of 1-Wire slaves. Instructions and a decision worksheet are included to identify the most cost-effective 1-Wire master for the application. The reader should be familiar with the basics of 1-Wire communication and microcontrollers.

MAX2120 DVB-S Half-NIM Tuner Reference Design

This reference design is a commercial Half-NIM DVB-S tuner that uses Maxim's MAX2120 satellite tuner IC. The reference design connects to the motherboard through a 12-pin connector. The downconverted satellite signal from the LNB is supplied to an active, discrete loop-through, which splits the signal into two paths. One signal goes to the MAX2120 and the other provides an additional output from the STB.

MAX2160 ISDB-T Reference Design

This reference design for the MAX2160 tuner plus demodulator IC demonstrates a compact daughter-board solution for the ISDB-T standard (single-segment). This design converts UHF band signals (470MHz to 770MHz) to a MPEG-2 transport stream. The solution is intended for portable applications, such as cell-phone TVs and PDAs.
