SFP-1GBT-09
SFP Copper Transceiver 1000Base-X to 1000Base-T
GBIC with SyncE
DESCRIPTION
The Bel SFP-1GBT-09 transceiver is an internally configured 1000Base-T SFP that requires the host system
to provide GBIC interface. The PHY interfaces directly with SerDes interface. The host interface transmits
and receives serial data differentially at 1.25 Gbps. The copper interface is full featured as advertised full/half
duplex and 1000Base-T wire speed.
FEATURES / BENEFITS

•
Designed with Broadcom’s BCM54616S
chipset
Complies with IEEE 802.3, 802.3u, and
802.3ab specifications
Configured for operation with a GBIC
compliant host
Supports SyncE functionality
Conforms to Multi-Source Agreement (MSA)
specifications for SFP transceivers
(Exceptions for SyncE features)
Supports IEEE 802.3u and IEEE 802.3ab
auto–negotiation 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 the DC offset from the
input signal
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
The BCM54616S physical layer IC (PHY)
can be accessed via I2C interface:
PHY address = “ACh”
EEPROM memory address = “A0h”
The SyncE feature can be accessed via I2C
Interface:
Address = “A2h”
