-Chip switching" application-specific ic asic. In addition to eight ports, MDS 9134 provides the flexibility to expand from 24 ports to 32 ports. 2 10-Gbps ports can be activated to meet the density requirements of the optical fiber switch above the rack and the edge access switch in the enterprise SAN. The product adopts a non-congested architecture and supports all 32 4-Gbps ports and two 10-Gbps ports running at the same time at the same speed. The MDS 9134 provides 10-Gbps ports that suppor

in a centralized manner when the data volume reaches a certain amount to improve system performance. FIFO can be integrated into the chip. When the system requires a large buffer, it can also be implemented using a separate Ram. The b0x serial transceiver consists of a 16 B FIFO and a data Cer. The data to be transmitted is written into the FIFO, assigned to the transmitter, and finally sent out from the transmission pin shift, achieve the purpose of

. There are two types of USB controllers available on the market: single-chip microcomputer (MCU) with USB interface or pure USB interface chip. I chose cygnal's c8051f320 chip as the former chip. Cygnal's c8051f series single-chip microcomputer is an integrated hybrid signal chip system Soc. It has a fully compatible Microcontroller with the MCS-51 kernel and instruction set, with a USB transceiver, fully compliant with USB protocol 2.0, supports 12

As the center of Internet cafes, vrouters are dominant. Next, let's talk about how to set up the Internet cafe router. Internet cafes provide a broadband optical cable from a network supplier. The bandwidth of this optical cable is faster than that of the Household Network. Optical Cable through the optical transceiver Access Router, the router can be connected to several switches, a common switch has 24 ports, one of which has an import, 23 outlets,

. The CC1110 chip contains the CC1100 RF transceiver and is embedded with an enhanced 51 kernel microcontroller. The chip is embedded with 32 KB programmable Flash memory, 4 kb sram memory, 8-Channel 8 ~ 14-bit A/D converter, 1 16-bit timer and 3 8-bit timer, 2 UART/SPI, RTC and 21 universal I/0. The CC1100-based high-performance wireless transceiver works at 433 MHz and features high frequency stability a

1.XILINX GTX Introduction The GTX is a low-power gigabit transceiver on the Virtex series FPGA, and the GTX operating bandwidth range on the V6 chip is 750mb/s to 6.6GB/S, enabling two-way transmission and transceiver bidirectional independence. The GTX receive and transmit directions are made up of both PMA and PCs, and PCs provides rich physical coding layer features such as 8B/10B encoding, and the PMA i

mode, the NIC converts the serial data and parallel data. Before sending data, the network adapter needs to talk to the receiving network adapter to determine the maximum size of data to be sent, the size of the data to be sent, the interval between the two sent data, the waiting time for confirmation, and each maximum data volume and data transmission speed that the network adapter can withstand before the overflow.I. basic structure of the network cardNic includes hardware and firmware progra

Q: How to implement a Single-Chip Ethernet microcontroller? A: The trick is to integrate the microcontroller, Ethernet Media Access Controller (MAC), and physical interface transceiver (PHY) into the same chip, which can remove many external components. This solution enables good matching between MAC and PHY, and reduces the number of pins and chip area. The Single-Chip Ethernet microcontroller also reduces power consumption, especially when the power

/11. 0592/1000000 s Single-Chip Microcomputer machine cycle T3 = 12 * t2 T1/T3 = 96 That is, for the serial port of 9600bps, the single-chip microcomputer samples it at a rate of 96 times. If the MCU crystal oscillator is used incorrectly, the serial port will receive an error code. --------------------------------- RS485 and rs422 RS485 bus, when the communication distance is dozens of meters to kilometers, widely used RS-485 serial bus standard.

choose excellent performance.Of course, some manufacturers also associate extended distance support with multimode optical fiber 1300 nm transceiver, such as 1000base-lx. As no 1300 nm source conditions are specified in any standard, multiple methods for producing such transmitters may form the activation of various multimode optical fibers.Therefore, these claims must indicate various possibilities for spontaneous activation, or must rely on externa
