Five gigabit ports
All five ports run gigabit over copper, and each one wired to an RJ45 jack needs gigabit-rated magnetics; see our gigabit Ethernet transformers.

JL6105 Gigabit Ethernet Switch IC
JL6105 provides five external gigabit ports with no host uplink, in a QFN88 package at 10 by 10 millimetres. It runs from a 1.1 volt core rail, so confirm the power tree provides it before committing the design.

Series overview
JL6105 Ethernet switch IC for gigabit expansion
The JL6105 Ethernet switch IC forwards traffic among five gigabit copper ports, with no MAC interface for a host processor. That makes it a 5 port gigabit switch IC for unmanaged desktop switches and port expansion inside equipment, in QFN88 at 10 × 10 mm and a commercial grade. For five ports at 100M, see the JL5105.
No host bus
Interface mode and MAC voltage are listed as NA, so no host bus is routed. If a processor must join the network, the JL6107 adds uplink ports.
A larger QFN88 body
JL6105-NC uses QFN88 at 10 × 10 mm. A gigabit port uses four signal pairs against two at 100M, so expect more routing than on a 100M five-port board.
Supply rail
The external supply is listed as 1.1 V for JL6105-NC. Size that rail for five active gigabit ports from the datasheet power figures.
Applications
Where the JL6105 Ethernet switch IC is used
Choose it when gigabit devices share one link and no processor needs a port.
Gigabit desktop switches
Five-port gigabit desktop switches connect a home router to a PC, NAS, TV and game console.
Media furniture and AV racks
A TV cabinet or AV rack can bring in one gigabit cable and share it among a streamer, console and smart TV.
Under-desk switches
An under-desk switch turns one office network outlet into several gigabit ports for a workstation, phone and printer.

FAQ
Questions on the JL6105 Ethernet switch IC
Sourcing, temperature limits and design files.
What is JL6105 suited to?
Gigabit port expansion where the host controller does not need to be on the network. Five external ports at gigabit speed in a QFN88 package covers small switch modules and internal expansion. If the host must send or receive traffic, compare the JL6107 with its two uplinks.
What changes going from 100M to gigabit?
Signal integrity requirements tighten on the differential pairs, magnetics must be rated for gigabit, and power consumption rises. The layout has less tolerance for impedance discontinuities and length mismatch. Plan for the extra thermal load and verify link quality on a prototype.
What supply does it need?
It is listed as running from a 1.1 volt core rail. Confirm the rail, its tolerance and the required sequencing from the datasheet before the power tree is fixed, because a device of this type will not start at all if the core supply is absent or arrives in the wrong order.
How does it compare with JL6107?
JL6105 has five external gigabit ports and no uplink, in QFN88 at 10 by 10 millimetres. JL6107 adds two uplinks and comes in LQFP128 at 14 by 14, with fibre support on its S variants. Decide first whether the host needs to join the network.
How do I request samples or a quote?
With a complete part number, send the part number, quantity, delivery region and the date you need it. If you are still selecting, send the external port count and confirm whether the host needs to be on the network.
Does VOOHU distribute the JL6105 Ethernet switch IC?
Yes. As an authorized JLSemi distributor, VOOHU supplies JL6105-NC for development and volume builds. Our FAE team can review the port circuits and the 1.1 V supply with your samples.
Is the JL6105 suitable for a cabinet or outdoor switch?
Where do I find the JL6105 package drawing and footprint?
In its datasheet (PDF), the only file the selector lists. No 3D model or PCB footprint is published, so draw the QFN88 land pattern from that drawing.
