The SN75ALS162DWRG4 is a high-speed fiberoptic interface transceiver capable of managing several communication applications across a range of datacom markets. It is a specialized 10/100 Mbps media access controller (MAC) that provides medium- and long-distance media segmentation functions, data retransmission capability, and high-speed protocols to enable system designers to benefit from increased bandwidth and enhanced protocol capabilities. This family of transceivers is designed for applications where the ultimate goal is multivendor interoperability and Fibre Channel interoperability. It supports physical layer communications and data-link layer operations and provides a range of applications from broadcast Ethernet to standard Fibre Channel protocols.

The SN75ALS162DWRG4 is a multi-channel media access controller (MAC) transceiver with multiple fiber optic (OF) transceivers, each capable of transmitting and receiving built-in link failsafe functions. It combines single-mode and multimode fiber optics with an onboard media access engine that enables multiple channels of operation. The transceiver supports 10Base-T and 100Base-T Ethernet and 100Base-SC Fibre Channel communications.

The SN75ALS162DWRG4 features an integrated frame format and includes a control port to allow network engineers to configure and manage the device. The interface includes four pins to link the controller with the external system, a VCO and an 8-bit address decoder.The four-pin interface includes an address (A1-8), a data (D0-7), and a write enable (WE) input port and an acknowledgement (ACK) output port. Data can be transferred serially or in parallel, depending on the particular application, and the data rate can be implemented through a control switch.

The SN75ALS162DWRG4 provides four simultaneous communications, each supporting a different data rate, providing an effective bandwidth of 400 Mbits/second. This capability enables transceiver operations to be integrated for more efficient communication operations. One of the advantages of using this type of transceiver is that it supports several popular network protocols, including Ethernet, Token Ring, Fiber Channel, and Fibre Channel over Ethernet (FCoE).

The SN75ALS162DWRG4 includes optical transmitters, receivers and digital logic circuitry to segregate media segmentation functions. The transceiver core’s digital logic circuitry performs the Fibre Channel Flow Control functions. The logic supplies the data rate and frame formatting to ensure the effective and reliable communication of data over the fiber optic links. The logic also supports the auto negotiation process between physical media interfaces.

The SN75ALS162DWRG4 features a built-in spread spectrum communication interface that meets the current 802.3ae standards for reliable communication over the fiber optic links. This feature allows the user to reduce the EMI interference from the data path to a lower level without sacrificing the real-time performance of the connection. The built-in EMI shielding provides enhanced performance for applications in challenging physical media environments.

The SN75ALS162DWRG4 is an excellent choice for high-speed, reliable communication over a variety of physical media interfaces. It offers immunity to electrical interference while providing reliable data paths on networks with high utilization rates. The transceiver supports the popular networking protocols and provides cost-effective solutions for today\'s converged networks.
