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.
Ethernet-Schnittstellenchips
JL2308 provides eight gigabit ports aggregated to the host over QSGMII, in an LQFP128 package at 14 by 14 millimetres. Confirm the host offers QSGMII and enough bandwidth, then plan the layout for eight pairs and the serial lanes.

By series
Series are separated by link speed, port count and the MAC interface they present.
So wählen Sie aus
MAC interface first, then speed and ports, then fibre, then temperature and package.
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.
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.
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.
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
The MAC interface and the temperature suffix decide compatibility more than speed does.
100M, 1G or 2.5G depending on series. All devices also support 10Base-T on the copper side, so legacy links remain available.
Single port for most series, or eight ports on the JL2308 and JL2388. Eight-port devices need a QSGMII-capable host.
RMII, MII, RGMII, SGMII or QSGMII. This has to match the host controller exactly; no external conversion makes two of them equivalent.
100Base-FX on parts of the 100M range, 1000Base-X on JL2201 and 2500Base-X on JL4201. Several series are copper only, marked NA.
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.
From QFN24 at 4 by 4 millimetres up to LQFP128 at 14 by 14. Pin count rises with port count and interface width.
Vergleichen
Speed, port count and MAC interface together define which series fits a design.

Kategorieübersicht
The most common selection error here is starting from link speed. The MAC interface is the constraint that cannot be worked around.

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.
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.
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
Answers cover interface choice, fibre support, temperature grades and layout.
Over QSGMII, a serial interface that carries several links on one pair rather than running eight parallel interfaces. Your host controller must provide QSGMII and enough aggregate bandwidth for eight gigabit links. Confirm both before selecting an eight port device.
Controlled impedance, length matching and a continuous reference plane under the serial lanes. It is a high speed serial link, so it is less forgiving than a parallel interface. Follow the datasheet layout guidance and verify link quality on a prototype board.
Both are eight port gigabit devices with QSGMII in an LQFP128 package at 14 by 14 millimetres and the same temperature grades. Feature level differences are defined by their respective datasheets, so send your requirement and our engineers will set out which differences apply.
Each copper port needs its own magnetics, either discrete LAN transformers or RJ45 jacks with integrated magnetics. Plan the board area and the panel arrangement early, and follow the device reference circuit for the centre tap connection on each port.
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 host controller, confirmation that it provides QSGMII, the port count and the temperature range.
