Higher bandwidth connections are made by grouping 4 or 12 pairs together, for up to 3 GB/s full-duplex connections. InfiniBand is designed to be used over a Backplane, Copper wire or Fiber. The impedance for the PWB interface or cable interface is 100W. All inter-connections are Hot-Swappable on InfiniBand. The specification defines a data rate of 250MBytes/sec for both

electrical and optical signaling. That`s a 2. 5GHz signaling speed using 8B/10B [10 bits = 1 byte] Each IBA Packet [InfiniBand Architecture] begins with a Start-of-Frame [SOF], and ends with an End-of-Frame [EOF]. The Header field is made up of a Routing Header and a Transport Header. The Packet Payload follows the Header field. Two different Cyclic Redundancy Code [CRC] fields follow the Payload; ICRC [Invariant CRC] and VCRC [Variant CRC]. The Invariant CRC field covers the packets that do not change from source to destination, while the Variant CRC filed covers packets from link to link. Fill frames are used between packets. The maximum allowable Deterministic Jitter [JD] from the driver is 0. 17 UI [without pre-emphasis]. The Total Jitter [JT] allowed from the driver is 0. 35 UI. They reside with in a metal case to provide EMI shielding. The thickness of the PWB isn`t really defined, as long as it resides with in the EMI defined case.
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
