Module đồng SFP công nghiệp 1.25Gb/s, 10/100/1000BASE-T, RJ45 JHA Tech JHA3401
JHA3401 10/100/1000BASE-T copper SFP transceiver is high performance, cost effective module compliant with the Gigabit Ethernet and 10/100/1000BASE-T standards as specified in IEEE 802. 3-2002 and IEEE 802.3ab, which supporting 10/100/1000Mbps data- rate up to 100 meters reach over unshielded twisted-pair category 5 cable. The JHA3401 supports 10/100/1000 Mbps full duplex data-links with 5-level Pulse Amplitude Modula-tion (PAM) signals. All four pairs in the cable are used with symbol rate at 250Mbps on each pair. The JHA3401 provides standard serial ID information compliant with SFP MSA, which can be accessed with address of A0h via the 2-wire serial CMOS EEPROM protocol. The physical IC can also be accessed via 2-wire serial bus at address ACh.
