Series overview
Selecting a JL6110 Ethernet switch IC
The JL6110 Ethernet switch IC is built for gigabit switches with a fiber uplink: every part lists a 1000BASE-X optical port beside eight external copper ports and two uplink ports, listed as 8+2. The host interface is MII at 3.3 V, and the package is TQFP176 at 20 × 20 mm, in commercial and industrial grades. For five ports, see the JL6107 series; without uplinks, the JL6108.
MII at 3.3 V
The MAC interface voltage is 3.3 V, so a host with 3.3 V MII fits without the 1.8 V I/O that the JL6107 needs. Confirm MII timing and pin groups in the datasheet.
TQFP176 at 20 × 20 mm
Every part uses TQFP176 at 20 × 20 mm with a 1.1 V external supply listing. Budget board area for eight port circuits, two uplinks and the fiber interface.
Commercial or industrial
JL6110-PC covers 0 to 70 °C for offices and equipment rooms. JL6110-PI covers −40 to +85 °C for an industrial Ethernet switch IC in field cabinets with fiber links.
Applications
Where engineers use the JL6110 Ethernet switch IC
Eight copper ports plus fiber suit networks that span distance or electrical noise.
Industrial switches with fiber uplink
A DIN-rail or rack switch can link eight machines on copper and reach the control room over fiber; JL6110-PI is rated −40 to +85 °C.
Floor and campus distribution
A gigabit Ethernet switch IC with fiber lets a floor switch serve eight rooms or access points on copper and uplink to the building core.
Camera aggregation
Surveillance cabinets can gather gigabit cameras on the copper ports and send the combined traffic over a 1000BASE-X fiber link to the recorder.

Samples and quotations
Samples are available for evaluation, and selected parts are free of charge. Our FAE team will be glad to confirm the options for your project. Tell us the grade and quantity for a quotation, and we will confirm availability.
Migrating from another fiber switch
To move a design from another gigabit switch IC with fiber, send its part number and datasheet. Our FAE team checks the 1000BASE-X and MII interfaces, registers and layout, then suggests candidates, to be validated with samples before production.
Quality and company
VOOHU is ISO 9001 and ISO 14001 certified. Since 2018 VOOHU has supplied more than 1,500 customers, including 150+ listed companies. The eight copper ports each need magnetics and an RJ45 jack; see our gigabit Ethernet transformers.
FAQ
Questions about choosing a JL6110 Ethernet switch IC
Sourcing, fiber on each part and design files, in brief.
What makes JL6110 the most complete option?
It combines the highest port count in the gigabit range with two uplinks and 1000Base-X fibre support, in both commercial and industrial temperature grades. That covers managed switching, host access, cascading and a fibre uplink in one device, which no other part in the range does.
How do I use the fibre uplink?
Configure the 1000Base-X mode as described in the datasheet reference design and pair it with a matching optical module. Decide during schematic design whether a given link is copper or fibre, because the external circuit differs and retrofitting it into a finished layout is difficult.
What does TQFP176 demand from the design?
Twenty millimetres square with high pin count. You need space for eight gigabit pairs and their magnetics, the fibre interface, two uplinks and the decoupling network, planned as a whole. Follow the datasheet layout and thermal guidance and validate the assembly process on real boards.
Which temperature grades are available?
Both the PC suffix at 0 to 70 degrees and the PI suffix at minus 40 to 85 are listed, which makes this one of the few series in the range offering an industrial grade. Select against the enclosure temperature at the highest rated ambient.
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 port topology, whether you need a fibre uplink, the target optical module and the temperature range.
Can VOOHU supply the industrial JL6110-PI?
Yes. VOOHU is an authorized JLSemi distributor and supplies JL6110-PI, rated −40 to +85 °C, as well as JL6110-PC. Send the quantity and application, and our FAE team will help plan samples.
Does every JL6110 Ethernet switch IC include the fiber port?
Yes. Each part lists a 1000BASE-X optical port, unlike the JL6107, where only the S and SC parts do. Take the fiber interface circuit from the datasheet.
Is there a 3D model of the JL6110 TQFP176 package?
No. Only the datasheet (PDF) is listed for each part number, so draw the TQFP176 land pattern and 20 × 20 mm outline from its package drawing.
