A popular application for the voltage-controlled crystal oscillator is the forming of a phase-locked loop. Designing the VCXO for this application requires a ‘pullable’ quartz crystal.
A voltage-controlled crystal oscillator’s (VCXO) output frequency changes in direct proportion to the application...
Sanyo Denki redesigned all parts of the cooling fans like motor with magnetic circuit and structure with electrical circuit, impeller and frame so that fan has the best performance at assumed operating area and they have proceeded development of new low power consumption fan.
This document explains the differences...
XP Power offers advice on power supply design, which could help with your next design. Most electronics engineers can design an AC/DC power supply based on first principles but it’s through careful refinements in the design that real reliability and efficiency improvements appear.
In this whitepaper, XP Power...
When transitioning from a traditional phone network to a voice over IP (VoIP) network, it is essential to recognize a key difference between the public switched telephone network (PSTN) and the private data network that will be called upon to take its place.
The PSTN is connected to a massive battery array that allows...
As with most engineering activities, choosing the right tool may have serious implications on the measurement results. The information below may help the readers make the proper accelerometer selection. The paper starts with the basic classifications and their technologies.

Power has always been a design consideration. Traditionally, though, a lower priority has been assigned to power than to most other variables (speed/performance, cost, time-to-market, risk, etc.). In today’s marketplace, however, power has become a very important component in the designer’s decision making...
The Knowles PDW05758 from DLI is a surface mount, thin film power divider employing a three section Wilkinson topology. This power divider utilizes a proprietary DLI temperature stable ceramic, low loss conductors, and integrated resistors. The device provides exceptional performance in a tiny package compatible with standard...
Resistors used in modern electronics often experience transients (e.g. lighning strike) or pulse loads (e.g. inrush current), and thier ability to survive and operate properly in these applications is a criterial issue.
For most applications, wirewound resistors provide the very best capability in these conditions,...
This White Paper describes how the new VIA PFM, a power component that performs the front-end AC-DC conversion required in many systems, allows the application of Vicor’s Power Component Design Methodology from AC to the Point of Load (PoL). The performance of the component is described, highlighting how the VIA...
This article details the common problems plaguing analog voltage mode control loops and shows how a digital control loop is able to provide bandwidth that was previously dismissed as unobtainable. By walking through the variables associated with stability and comparing it to an analog control system, it can be seen that...
Any engineer involved with portable or handheld products knows that minimizing power consumption is an absolute requirement for today’s designs. But only the veterans understand the subtle yet important details that can stretch a systems’ battery life to the maximum.
In this white paper Lattice Semiconductor...
Racks organize IT equipment, such as servers and network switches, into standardized assemblies that make efficient use of space and other resources. Depending on the options you choose, they can also improve power protection, cooling, cable management, device management, physical security, mobility, ease of installation...
Low-power electrical transients generated within a facility are the primary cause of failure to AC/DC power supplies. These transients reduce the life of power supplies and create unplanned downtime.
This document will explain why these transients cause failure and outline how placing high-power transient voltage...
The use of different crystal cuts in frequency control applications result in different performance. This paper will discuss the AT cut and SC cut performance along with cost trade-offs of the two cuts. Since the SC is primarily used for ovenized applications, this will be the focus.
The SC and AT cuts have different...
