ABCU-57xxxxZ Family 10/100/1000BASE-T 1.25 GBd Small Form Pluggable Low Voltage (3.3 V) Electrical Transceiver over Category 5 Cable Data Sheet Description Features RoHS-6 Compliant (see Table 1) The ABCU-57xxxxZ family of electrical transceivers from Avago Technologies offer full-duplex throughput of 1000 Designed for Industry-Standard, Small Form Factor Mbps by transporting data over shielded and unshielded Pluggable (SFP) Ports twisted pair category 5 cable with 5-level PAM (Pulse Compliance with IEEE 802.3:2005 Amplitude Modulation) signals. Custom RJ-45 connector with integrated magnetics The Avago Technologies 1000BASE-T module takes sig- Link lengths at 1.25 Gbd: up to 100 m per IEEE802.3 nals from both the twisted pair category 5 cable and the Low power, high performance 1.25 Gbd SerDes inte- SerDes interface. Pin count overhead between the MAC grated in module and the PHY is minimized, and Gigabit Ethernet opera- Single +3.3 V power supply operation tion is achieved with maximum space savings.
