Scheme-it
Introduction
Schematic Drawings
Use schematic symbols to layout the components of your circuit and make electrical connections. With symbols ranging from amplifiers to vacuum tubes, as well as the ability to build custom symbols, you are able to design nearly any circuit. Access to Digi-Key's extensive part database also allows you to browse and assign orderable part numbers.
Diagram Building
Use the system blocks to refine your idea at a conceptual level. The higher-level components are there to help you plan out the broader intentions of your idea. This powerful block chain library allows you to quickly layout the function of circuit. Once your design is ready, save and share with your colleagues.
Flow Chart Creation
The flow chart creation option will help transition your concept to a design. Use the library of arrows, shapes, UML symbols, and more to sort out the flow and annotate each stage. Insert a textbox, math function/formula, image, or link to help illustrate the objectives and make your plan easy to follow.

9FGV0241 PCI-Express Clock Generator
This reference design is based on IDT's 9FGV0241 PCI-Express Clock Generator. The 9FGV0241 belongs to the series of Very Low Power PCI-Express clocking devices of IDT. It is a 2-output clock generator suitable for PCI-Express Gen 1, 2 and 3 applications. It features 2 output enables for clock management and supports 2 different spread spectrum levels in addition to spread off. It operates out of an 1.8V power supply with a typical power consumption of less than 50mW.
8V97051NLGI Low Power Wideband Fractional RF Synthesizer
This design features a low power wideband RF synthesizer that is used in GSM receiver cards. It has dual differential and open drain outputs with frequency range of 34.375MHz to 4400MHz(in continuous range). The logic compatibility is 1.8V while the the system is running on a single 3.3V supply. It has -143dBc/Hz Phase Noise (PN) performance at 1MHz Offset for every 1.1GHz output. It is also capable of mute function at RF_OUT that is accessible via mute pin or SPI command. It is low power with only 380mW average power consumption while RF_OUTB is not in used.
