Product Description
The TK-G1-RJ45 is a copper Small Form Pluggable (SFP) transceiver compliant with Gigabit Ethernet and 1000BASE‑T standards (IEEE 802.3‑2002 and IEEE 802.3ab). It supports 1000Mbps data rates over unshielded twisted‑pair Category 5 cable up to 100 meters.
The module uses 5‑level Pulse Amplitude Modulation (PAM) signals on all four pairs (250 Mbps per pair) for full‑duplex data links. It provides standard serial ID information per SFP MSA (accessible via 2‑wire serial bus at address A0h). The physical layer IC can also be accessed via the same bus at address ACh.
- Up to 1.25Gb/s bi‑directional data links
- Hot‑pluggable SFP footprint
- TX Disable and RX LOS (or without LOS) function
- Fully metallic enclosure for low EMI
- Low power dissipation: 1.05 W typical
- Compact RJ‑45 connector assembly
- Access to physical layer IC via 2‑wire serial bus
- 1000BASE‑T operation in host systems with SERDES interface
- Operating case temperature: 0°C to +70°C (commercial) or -20°C to +85°C (extended)
- 1.25 Gigabit Ethernet over Cat 5 cable

- Plug Seq.: Pin engagement sequence during hot‑plugging.
- TX Fault is not supported and is always connected to ground.
- TX Disable: Pin pulled up with 4.7kΩ. Low (0-0.8V): Transceiver on; High (2.0-3.465V) or open: Transceiver in reset.
- Mod‑Def 0,1,2: Pulled up with 4.7k-10kΩ on host board. Mod‑Def 0 grounded by module to indicate presence. Mod‑Def 1 = clock, Mod‑Def 2 = data for serial ID.
- RX_LOS: LVTTL compatible. Can be enabled/disabled (see ordering). When not used, tied to ground via 100Ω.
- RD-/+: AC coupled 100Ω differential outputs, terminate with 100Ω at host SERDES.
- TD-/+: AC coupled 100Ω differential inputs with 100Ω termination inside module.
