Port notation
A figure such as 5+1 means five external ports plus one host uplink. A single figure such as 5 or 8 means external ports only, with no separate uplink.
Ethernet-Schnittstellenchips
JL5109 combines eight external 100M ports with one MII host uplink in a QFN88 package at 10 by 10 millimetres. It suits mid-size managed switches where the host must reach the network alongside a dense front panel.

By port topology
Port notation such as 5+1 means five external ports plus one host uplink.
So wählen Sie aus
Topology first, then speed, then the supply rails, then package and thermals.
Count the external ports you need, then decide whether the host has to send and receive traffic. If it does, you need a device with an uplink port.
The range covers 100M and gigabit. There are no 2.5G or faster devices here, so if the design needs those speeds, say so at enquiry.
Most devices need a low voltage core rail alongside the main supply. Confirm the rails and their sequencing before the power tree is fixed.
Packages run from QFN48 at 6 by 6 up to TQFP176 at 20 by 20 millimetres. Higher port counts concentrate more heat in one device.
Parameters
Port notation and the supply requirement are the two figures most often misread.
A figure such as 5+1 means five external ports plus one host uplink. A single figure such as 5 or 8 means external ports only, with no separate uplink.
100M on the JL51xx series, gigabit on the JL61xx series. Every device also supports 10Base-T on copper for legacy links.
MII on most devices with an uplink, RMII on the JL5104. Devices listed as NA have no dedicated host interface at all.
Typically a 3.3 volt main supply with a 1.1 volt core rail, or 1.1 volt alone on some gigabit parts. Missing a rail prevents the device starting.
1000Base-X appears on the JL6110 and on the S variants of the JL6107. Other devices in the range are copper only.
NC and PC suffixes cover 0 to 70 degrees; NI and PI cover minus 40 to 85. Not every series offers both grades.
Vergleichen
Port count and uplink presence separate the series more than speed does.

Kategorieübersicht
Almost every selection question on switch ICs comes down to the port notation and whether the host controller needs to be on the network.

The first figure is external ports facing the outside world. The figure after the plus is a host uplink, a dedicated interface for the controller on the same board. A device listed as 5 has five external ports and no uplink, so the host cannot send or receive traffic through it. That distinction eliminates half the range.
If the product only has to move traffic between its own front panel ports, a device with external ports only is simpler and cheaper to lay out. If the host has to participate, for management, for remote access or because it originates data, you need an uplink and the host must provide the matching MII or RMII interface.
Most devices here need more than one rail: commonly 3.3 volts for the main supply and around 1.1 volts for the core, and some gigabit parts run the core alone. Missing a rail, or sequencing them wrongly, prevents the device starting. Confirm the rails and sequence before the power tree is committed.
FAQ
Answers cover port notation, uplinks, supply rails and fibre support.
Eight external ports on the panel plus one MII uplink so the host controller can join the network, typically for management, remote access or host-originated traffic. It is the configuration for a mid-size managed switch where port density and host access are both required.
The listed part carries the NC suffix, covering 0 to 70 degrees. If your product needs an industrial range, tell us the required temperature and our engineers will confirm what is currently available, rather than assuming a grade exists because other series offer one.
Both provide eight external ports with an MII uplink in a QFN88 package at 10 by 10 millimetres. JL5110 has two uplinks rather than one, which allows a host connection and a cascade to another switch at the same time. Choose on whether you need that second link.
Eight copper ports each need magnetics and a controlled impedance pair to the connector, plus the MII uplink routing to the host. Decide the panel arrangement and the device placement early, then verify link stability and emissions on a prototype board.
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, the host interface and the operating temperature range you require.
