Product Description
RJ45 Gigabit SFP Module – 1000BASE-T, 1.25Gbps, 100m over Cat 6, Low EMI
Product Overview
The TK-G1-RJ45 is a hot-pluggable copper SFP transceiver designed for Gigabit Ethernet applications. It conforms to IEEE 802.3-2002 and IEEE 802.3ab (1000BASE-T) standards. The module operates at 1000Mbps data rate over Category 5 unshielded twisted-pair cable with a maximum reach of 100 meters.
Signal transmission uses 5-level Pulse Amplitude Modulation (PAM) on all four wire pairs (250 Mbps per pair) for full-duplex links. The module includes serial ID functionality per SFP MSA, accessible via a 2-wire serial bus at address A0h. The physical layer IC can also be accessed at address ACh.
Key Features
- Data rate up to 1.25Gb/s bidirectional
- SFP MSA compliant, hot-pluggable
- TX Disable and RX LOS (or no LOS)
- Full metal housing for low electromagnetic interference
- Typical power consumption: 1.05 W
- Compact RJ-45 connector
- 2-wire serial bus access to physical IC
- Supports 1000BASE-T on host systems with SERDES interface
- Operating case temperature: 0℃ to +70℃ (commercial) or -20℃ to +85℃ (extended)
Applications
- 1.25 Gigabit Ethernet transmission over Cat 5 cable

Notes on Pin Functions
- Plug Seq.: Pin engagement order during hot-plugging.
- TX_FAULT: Permanently low (not supported).
- TX_DISABLE: Internal 4.7kΩ pull-up. Low (0-0.8V) → transceiver on; High (2.0-3.465V) or open → reset.
- Mod-Def 0/1/2: Host pulls up with 4.7k-10kΩ to Vcc. Mod-Def 0 = module present (grounded). Mod-Def 1 = clock, Mod-Def 2 = data.
- RX_LOS: LVTTL output. Can be disabled (order option). If unused, tied to ground via 100Ω.
- RD ± / TD±: AC coupled 100Ω differential lines. Host SERDES must terminate RD± with 100Ω; TD± have internal 100Ω termination.
