So what is this chip? Maybe it’s simply four comparators, but they could have a specific purpose. The chip could be a converter for four differential input signals, e.g. DCS (Differential Current Switch) logic. Another chip in the family seems to be Emitter-Coupled Logic, so this chip could be four ECL inverters (but it doesn’t make sense to have four pins for the reference voltage). It’s a bit puzzling that two comparators have inverted and noninverted outputs, while two have single outputs.
App note from ON Semiconductors about the need for long cables for high speed Type-C and Type-A connectors. Link here (PDF)
With the increasing requirement for high speed transfer of larger bulk of data, better quality video and power delivery, change over from analog to digital videos, bi−directional transfers, it become essential to use a proper cable that delivers the data correctly between external hard drives and other systems or end products.
The use of Active cable becomes a necessity with increase in cable lengths of more than 5 meters, number of ports and data rates 10 Gbps and above. To match these using passive cables will become expensive with increased weight and thickness.
When I built the VE7BPO DC Receiver Mainframe recently, it wasn’t intended to end up as a final finished project. The intention was more to have it as part of an experimental platform. The little box that contains the DBM, diplexer, and AF amplifier that make up the mainframe will most likely stay largely the same, now that they are built and boxed up. However, the outboard functions of local oscillator and antenna filtering can swapped around and changed at will. The mainframe includes a spot for an onboard plug-in bandpass filter.
App note from Diodes Incorporated on their SBR technology which can supports ISO standard supply protection. Link here (PDF)
Electrical disturbances in an automotive environment present reliability and functional risks to the various electronic systems and components that may be exposed. Many modules, for example electronic control units (ECUs), have sensitive microcontrollers at their core and must be shielded to ensure reliable operation. High-voltage transient conduction can be introduced along supply lines by many sources including: ignition systems, inductive components, unexpected conditions such as faults, and connection/disconnection of loads. Depending on the severity these can cause anything from system malfunctions to irreparable component damage.
App note from Diodes Incorporated on their AL8860Q LED driver with built-in faults protection. Link here (PDF)
The AL8860Q is a hysteresis mode DC-DC buck LED driver, designed for driving single or multiple series connected LEDs in automotive lamps. In some circumstances the LED string should become in fault status such as open-circuit, short-circuit, LED string anode shorted to GND, which may result in damage to the system and battery. For safety and reliability, the total solution in automotive LED lighting application must take these fault conditions in consideration.
