SFP-1GBT-05 Bel Fuse

SFP-1GBT-05 SFP Copper Transceiver 10/100/1000Base-T to SGMII The Bel SFP-1GBT-05 transceiver is an internally configured 10/100/1000Base-T SFP module for SGMII host interfaces. The host interface transmits and receives serial data differentially at 1.25Gbps. The copper interface is advertised as full duplex and will auto-negotiate to 10/100/1000 Base-T. Key Features & Benefits Designed with Broadcoms BCM54616S chipset Complies with IEEE 802.3, 802.3u, and 802.3ab specifications Conforms to Multi-Source Agreement (MSA) specifications for SFP transceivers Supports IEEE 802.3u and IEEE 802.3ab autonegotiation features to allow networking equipment to automatically determine and adjust the required settings Operates in extended temperature range of -40 to +85 C Automatically compensates for baseline wander by removing DC offset from the input signal Assembled with low EMI emissions IC and fully metallic housings Automatic dependent interface (DI) crossover, eliminating the need for crossover cables or cross-wire (MDIX) ports Bail latch provides ease of extraction Compact RJ45 connector assembly Data is scrambled to reduce radiated emission Power consumption is 610mW typical Fully RoHS compliant 2 The BCM54616S physical layer IC (PHY) can be accessed via I C interface: PHY address = ACh EEPROM address = A0h Applications 10/100/1000 Mbps data rate in excess of 100 meters of Category 5/5e cable Industrial temperature environments -40 to +85 C Networking equipment Switch-to-switch interface Routers Regulatory and Standards Compliance Compliant with IEEE 802.3:2000 FCC Part 15, Class A EN55022 Class A CE E55024 Immunity standard and ESD Bel Modules +44 1622 757 395 28 Turkey Court, Turkey Mill, Ashford Road techhelp belf.com Maidstone Bel ME 14 5PP UK belfuse.com 2017 Bel Power Solutions, Inc.
