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.
Gamme de circuits d’interface Ethernet
JL2201 is a single port gigabit PHY with RGMII on the MAC side and 1000Base-X fibre support, in a QFN48 package at 6 by 6 millimetres. It is the copper and fibre option at gigabit speed in this range.

By series
Series are separated by link speed, port count and the MAC interface they present.
Comment sélectionner
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.
Comparer
Speed, port count and MAC interface together define which series fits a design.

Présentation de la catégorie
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.
Both are single port gigabit devices with an RGMII MAC interface. JL2201 adds 1000Base-X fibre support and comes in a larger QFN48 package at 6 by 6 millimetres, against QFN40 at 5 by 5 for the JL2101, which is copper only. Choose on whether you need fibre.
Configure it as described in the datasheet reference design and pair it with a matching optical module. The external circuit for a fibre port differs from a copper port, so decide which you need during schematic design rather than trying to accommodate both late in layout.
Whether both modes can operate simultaneously, or switch automatically, depends on the device configuration described in the datasheet. Do not assume both are available at once simply because both are listed. If your design needs a specific arrangement, confirm it with our engineers.
The listed parts cover 0 to 70 degrees and minus 40 to 85 degrees, identified by the NC and NI suffixes. Select against the temperature inside the enclosure at the highest rated ambient, including the heat generated by the board itself.
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 MAC interface, whether you need a fibre port and the target optical module.
