描述 and octal (eight-channel) XRT83SL38. These devices are ideal for the high bandwidth needs from the backbone or Core to the Metro Area Network. OEM products for this technology include Multi-Service Provisioning Platforms (MSPP), access devices, media gateways, routers frame relay access devices, and wireless base stations. What is R3 TechnologyTM? Exar's R3 TechnologyTM (Reconfigurable, Relayless Redundancy) delivers key innovative features to customers designing T1/E1/J1 interface cards. The devices are Reconfigurable -- integrated termination supporting all common T1/E1/J1 line impedances (75-120 ohms) enabling customers to build boards with a single bill-of-materials. Exar's on-board reconfigurable clock synthesizer allows manufacturers to build hardware in advance and configure the product (in software) for the particular application or market at the time of shipment. Conventional approaches require fixed settings - T1, or E1, or J1, forcing customers to determine device settings before manufacturing, and carry all configurations in inventory even if they are not immediately required. Also, the series employs Relayless Redundancy eliminating the need for external relays for 1:1 and 1+1 applications by establishing a back-up channel that is brought on-line in event of failure.
