Link speed
100M, 1G or 2.5G depending on series. All devices also support 10Base-T on the copper side, so legacy links remain available.

By series
Ethernet PHY series by speed and ports
Series are separated by link speed, port count and the MAC interface they present.
So wählen Sie aus
Selecting an Ethernet PHY in four steps
MAC interface first, then speed and ports, then fibre, then temperature and package.
- 01
Start from the MAC interface
Confirm what your host controller provides: RMII, MII, RGMII, SGMII or QSGMII. These are not interchangeable, and the wrong choice cannot be fixed in software.
- 02
Fix speed and port count
100M, 1G or 2.5G, and one port or eight. Eight-port devices aggregate to the host over QSGMII, so confirm the host has that bandwidth.
- 03
Decide on fibre
Some series support 100Base-FX or 1000Base-X, others are copper only. If the design needs a fibre port, check the specific part number rather than the series.
- 04
Pick the temperature grade
Suffixes separate 0 to 70, minus 40 to 85 and minus 40 to 105 degrees. Choose against the enclosure's internal temperature, not the room.
Parameters
Reading Ethernet PHY specifications
The MAC interface and the temperature suffix decide compatibility more than speed does.
Port count
Single port for most series, or eight ports on the JL2308 and JL2388. Eight-port devices need a QSGMII-capable host.
MAC interface
RMII, MII, RGMII, SGMII or QSGMII. This has to match the host controller exactly; no external conversion makes two of them equivalent.
Fibre support
100Base-FX on parts of the 100M range, 1000Base-X on JL2201 and 2500Base-X on JL4201. Several series are copper only, marked NA.
Temperature grade
The suffix carries it: NC for 0 to 70, NI for minus 40 to 85, NE for minus 40 to 105 degrees. Confirm the grade on the exact part number.
Gehäuse
From QFN24 at 4 by 4 millimetres up to LQFP128 at 14 by 14. Pin count rises with port count and interface width.
Vergleichen
Ethernet PHY series side by side
Speed, port count and MAC interface together define which series fits a design.

Anwendungsprüfung
Where these Ethernet PHY devices are used
Confirm the host interface, the link speed and the environment the board runs in.
Industrial controllers and gateways
- Confirm the host MAC interface and choose the minus 40 to 85 or minus 40 to 105 grade to suit the cabinet temperature.
EtherCAT and fieldbus devices
- The JL1111 range includes an EtherCAT variant. Confirm the protocol requirement and the MII timing before committing to a part.
Multi-port switch boards
- Eight-port devices aggregate over QSGMII. Verify the host provides QSGMII and that the layout can carry the serial lanes cleanly.
Fibre uplinks and media converters
- Check which specific part number supports 100Base-FX, 1000Base-X or 2500Base-X, then confirm the optical module matches.

Kategorieübersicht
Choosing an Ethernet-PHY: interface before speed
The most common selection error here is starting from link speed. The MAC interface is the constraint that cannot be worked around.

The MAC interface decides compatibility
RMII, MII, RGMII, SGMII and QSGMII are different electrical and timing arrangements, not tiers of the same thing. A host that provides RGMII cannot drive an RMII device, and no software setting bridges them. Establish what your controller offers first, because it eliminates most of the range before speed is even considered.
Copper, fibre, or both
Every device here supports copper, including 10Base-T. Fibre is selective: 100Base-FX appears on parts of the 100M range, 1000Base-X on the JL2201 and 2500Base-X on the JL4201. Fibre support is stated per part number rather than per series, so one variant of a series may have it and another may not.
Temperature grade is in the suffix
The letters after the base number carry the rating. NC covers 0 to 70 degrees, NI covers minus 40 to 85, NE covers minus 40 to 105. Select against the temperature inside the enclosure at the highest ambient the product is rated for, not against room temperature.
FAQ
Ethernet PHY questions engineers ask
Answers cover interface choice, fibre support, temperature grades and layout.
What are the JL2121 specifications?
Specifications are confirmed per part number at enquiry rather than published as a fixed list here. Send your host MAC interface, required link speed, temperature grade and expected volume, and our engineers will confirm which current options apply before you commit the design.
How does it compare with JL2101 and JL2201?
All three sit in the gigabit part of the range. JL2101 presents RGMII and is copper only; JL2201 presents RGMII with 1000Base-X fibre support. For a direct comparison with JL2121, send your requirement and our engineers will set out the differences that matter to your design.
Can I design this in now?
Confirm availability before committing. For any device where you need long term supply, ask about lifecycle status and lead time at the same time as the technical specification, so the design decision and the supply decision are made together.
What should I send to get an answer quickly?
The host controller and its MAC interface, the required link speed and port count, whether you need a fibre port, the operating temperature range and your expected annual volume. With those five, our engineers can usually respond with a shortlist immediately.
How do I request samples or a quote?
Send the host MAC interface, required speed, temperature grade, quantity and delivery region. Because part level detail for this series is confirmed at enquiry, a sales engineer will come back with the applicable part numbers before samples are arranged.
