This project has been designed to interface an EIA-232 channel to an EIA- 485 half-duplex bus. We should do so because EIA-485 offers more features than 232, especially where we apply a long distance wired communication involving more than two devic

The SP3481 and the SP3485 are 2 members in the family of +3.3V low power half-duplex transceivers that meet the specifications of the RS-485 and RS-422 serial protocols. These devices are pin-to-pin compatible with the Sipex SP481, SP483, and SP485
The XR16L7881 (788), formerly XR16L758, is a 5V and 3.3V with 5V tolerant inputs octal Universal Asynchronous Receiver and Transmitter (UART). The highly integrated device is designed for high bandwidth requirement in communication systems. A new fe
The document describes the design of the MAC used in the Opencores 10 Gb Ethernet project. 10 Gb Ethernet is part of the IEEE 802.3 standard. It is essentially a faster version of the Ethernet where half duplex operation mode is not supported. The M
The authors consider a cooperative communication system where multiple sources transmit data to multiple destinations, being helped by multiple half-duplex relay nodes: relay nodes perform ‘amplify and forward’ as their cooperative technique, with t
The XR16C8641 (864) is an enhanced quad Universal Asynchronous Receiver and Transmitter (UART) each with 128 bytes of transmit and receive FIFOs, transmit and receive FIFO counters and trigger levels, automatic hardware and software flow control, au
手册好下载，应用指南难下载呀 The ST7538 is a Half Duplex synchronous/asyn- chronous FSK Modem designed for power line communication network applications. It operates from a single supply voltage and integrates a line driver and a 5V linear regulator. The device o
The STE100P, also referred to as STEPHY1, is a high performance Fast Ethernet physical layer interface for 10Base-T and 100Base-TX applications. It was designed with advanced CMOS technology to provide a Media Independent Interface (MII) for easy at
The AK2360A is a radio scrambler IC device suitable for half-duplex communication. As the scrambler method, a simple frequency inversion method is used in which audio signal components are inverted about the carrier frequency by using the double bal
The CMX7131 and CMX7141 are half-duplex processor IC platforms built on FirmASIC® technology and are suitable for use in digital radio and dual-mode (analogue/digital) systems, including dPMR, dPMR®/PMR446, DCR and NXDN™ radio designs. Alternatively
In this paper, we compare the throughput and delay performance between the full-duplex and half-duplex CSMA/CD EPON systems by theoretical derivation and simulation. We conclude that it's preferable to implement the full-duplex system.
