1000Base-T SFP Transceiver_光模块_上海伯唐通信设备有限公司

DeSCRJPTion:

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

Interface:

All high-speed signals are AC-coupled internally.

Parameter	Symbol	Min	Typ	Max	Units	Notes/Conditions
Data Rate	BR	10		1,000	Mb/sec	IEEE 802.3 compatible. See Notes 2 through 4 below
Cable Length	L			100	m	Category 5 UTP. BER <10-12

Notes:

1. Clock tolerance is +/- 50 ppm

2. By default, the BDTR-GB-P is a full duplex device in preferred master mode

3. Automatic crossover detection is enabled. External crossover cable is not required

4. 1000 BASE-T operation requires the host system to have an SGMII interface with no clocks, and the module PHY to be configured per Application Note AN-2036. With a SERDES that does not support SGMII, the module will operate at 1000BASE-T only.
