Description Baudcom’s BDTR-GB-PxRC Copper Small Form Pluggable
(SFP)transceivers is high performance, cost effective module
compliant with the Gigabit Ethernet and 1000- BASE-T standards as
specified in IEEE 802. 3-2002 and IEEE 802.3ab, which supp- orting
1000Mbps data- rate up to 100 meters reach over unshielded
twisted-pair category 5 cable. The module supports1000 Mbps full
duplex data-links with 5-level Pulse Amplitude Modulation (PAM)
signals. All four pairs in the cable are used with symbol rate at
250Mbps on each pair. The module provides standard serial ID
information compliant with SFP MSA, which can be accessed with
address of A0h via the 2wire serial CMOS EEPROM protocol. The
physical IC can also be accessed via 2wire serial bus at address
A0h. Features: - Up to 1.25Gbps bi-direction data links
- 100m transmission over unshielded twistedpair (UTP) Category 5
Cable
- Support intelligent auto-negotiation 1000BASE-T operation in host
systems with
- SGMII interface
- Hot-pluggable capability
- SFP/GBIC form with compact RJ-45 connector
- Very low EMI and excellent ESD protection
- +3.3/5V Single power supply
