The output of the preamplifier goes through 2 electronically tuned transistors. Finally, the output goes through to get to the rx mixer. For 2 m rx, the PIN diode bias is provided by the PA unit to 2 m preamplifier. Aircraft band Rx path (108-154 MHz) is the same as that of the 2 m path on the PA unit. On the MAIN unit, it goes through the same ...
The USI is a multi-purpose hardware communication module. With appropriate software support, it can be used to implement an SPI , [ 79 ] I²C [ 80 ] [ 81 ] or UART [ 82 ] interface. USART peripherals have more features than USI peripherals.
ARINC 818 (Avionics Digital Video Bus) is a point-to-point, 8b/10b-encoded (or 64B/66B for higher speeds) serial protocol for transmission of video, audio, and data. The protocol is packetized but is video-centric and very flexible, supporting an array of complex video functions including the multiplexing of multiple video streams on a single link or the transmission of a single stream over a ...

Front page of a floppy disk controller data sheet (1979) A datasheet, data sheet, or spec sheet is a document that summarizes the performance and other characteristics of a product, machine, component (e.g., an electronic component), material, subsystem (e.g., a power supply), or software in sufficient detail that allows a buyer to understand what the product is and a design engineer to ...
The 817 series (817系) is an AC electric multiple unit (EMU) train type operated on commuter and local services by Kyushu Railway Company (JR Kyushu) in Japan since 2001. The design was based on the earlier 815 series, with transverse seating replacing the previous longitudinal seating, [2] although later variants reverted to longitudinal seating.
An interface control document (ICD) in systems engineering [1] and software engineering, provides a record of all interface information (such as drawings, diagrams, tables, and textual information) generated for a project. [2] The underlying interface documents provide the details and describe the interface or interfaces between subsystems or ...
Digital circuitry is used to sequence the outputs from each module into the final pattern. The circle is internally generated as a square and cropped according to coordinates defined in a 264x252 grid defining half of the circle. The original used magnetic core to store data for the circle, essentially a very small core rope memory. Suitable ...
