The Bel SFP-1GBT-05 transceiver is an internally configured 10/100/1000Base-T SFP that requires the host system to
provide SGMII 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.

SFP Copper Transceiver 10/100/1000Base-T SGMII
SFP-1GBT-05
Rx_LOS is always ENABLE.
High —> Not linked.
Low —> Linked to link-partner.
Customer’s MAC should be setup for SGMII interface with Auto-Negotiation and the preferred mode of operation. There
is no need for accessing the PHY registers of the Broadcom PHY of the SFP-1GBT-05 Transceiver.
Bel’s Copper SFP-1GBT-05 Transceiver will automatically detect the advertised speed and mode of operation via the host
of the link-partner.
Default is 1000Base-T (Full-Duplex or Half-Duplex).
Bel’s Copper SFP-1GBT-05 Transceiver will automatically detect advertised 100Base-Tx speed and mode of
operations (Full-Duplex or Half-Duplex) from the MAC and link to its link-partner.
Bel’s Copper SFP-1GBT-05 Transceiver will automatically detect advertised 10Base-T speed and mode of
operation (Full-Duplex or Half-Duplex) from the MAC and link to its link-partner.
Depending on the condition of the MAC configuration, the SFP-1GBT-05 Transceiver can also be forced to operate at the pre-
ferred speed and mode of operation by accessing the Broadcom PHY registers via 0xAC” address:
1000Base-T Full-Duplex and/or Half-Duplex — by default.
Forcing the SFP-1GBT-05 to operate at 100Base-TX Full-Duplex and/or Half-Duplex:
1. Force Full-Duplex mode:
Write PHY register 00h to 0x2100h. (Force copper operate at 100Base-Tx Full-Duplex mode)
2. Force Half-Duplex mode:
Write PHY register 00h to 0x2000h. (Force copper operate at 100Base-Tx Half-Duplex mode)
3. Auto-Negotiation mode:
Write PHY register 09h to 0x0000. (Disable 1000Base-T ability)
Write PHY register 00h to 0x1340. (Restart Auto-Negotiation)

Forcing the SFP-1GBT-05 to operate at 10Base-T Full-Duplex and/or half-duplex
1. Force full-duplex mode:
Write PHY register 00h to 0x0100h. (Force copper operate at 10Base-T Full-Duplex mode)
2. Force half-duplex mode:
Write PHY register 00h to 0x0000h. (Force copper operate at 10Base-T Half-Duplex mode)
3. Auto-Negotiation mode:
Write PHY register 09h to 0x0000. (Disable 1000Base-T ability)
Write PHY register 04h to 0x0061. (Disable 10Base-T and 100Base-Tx ability)
Write PHY register 00h to 0x1340. (Restart Auto-Negotiation)
SGMII-Copper to GBIC:
If the GBIC Interface is required, Bel would recommend the SFP-1GBT-06 Transceiver for installation.
However, SFP-1GBT-05 Transceiver can also be configured to operate in GBIC (1000Base-X to 1000Base-T) interface by
accessing the Broadcom PHY registers via 0xAC”:
1. Write register 18h, shadow 07h bit [7] = 0 (Disable RGMII mode)
2. Write register 1Ch, shadow 1Fh bit [0] = 1 (Enable fiber register bank)
3. Write register 00h, bit [11] = 1 (Power-down SerDes interface)
4. Write register 1Ch, shadow 1Fh bit [2:1] = 11 (Configure the BCM54616S in GBIC mode)
5. Write register 00h, bit [11] = 0 (Power-up SerDes interface)
6. Write register 1Ch, shadow 1Fh bit [0] = 0 (Enable copper register bank)
7. Write register 00h, bit [11] = 0 (power up copper interface)
MAC Auto-Negotiation vs. MAC without Auto-Negotiation:
In case of MAC does not have Auto-Negotiation capability, the Auto-Negotiation of the SFP-1GBT-05 can also be disabled by
clear the Broadcom PHY register bit12 to “0”, then attempt to install the Bel’s SFP Transceiver.
