02Applications

Where SYT111B603EA2A1DFL is used

  • Switches and routers
  • Industrial controllers
  • IP cameras and NVRs
  • Embedded boards

Typical application

Ethernet PHYSYT111B603EA2A1DFLRJ45 jackTD+1 TX+TD−2 TX−RD+3 RX+RD−6 RX−ESD / TVS (optional)TX · 1CT:1CTRX · 1CT:1CTCTCTPHY-side CT: bias per PHY typeR1 75 ΩR2 75 ΩC1 1000 pF / 2 kVBob Smith terminationShield to chassis

The jack integrates the Ethernet magnetics: the PHY connects to it directly, and the transformer and common-mode termination sit inside the jack.

Check the datasheet for the centre-tap wiring your PHY needs and match the LED pins to the PHY's LED outputs.

Typical application for reference. Follow the PHY vendor's reference design.

Design notes

  1. 01Check tab orientation and LED positions against the enclosure opening.Tab Up / Tab Down and LED placement are the most common selection errors for RJ45 jacks.Check my layout →
  2. 02Bond the shield to chassis ground according to your grounding scheme.A floating or poorly bonded shield can make radiated emissions worse.EMC troubleshooting →
  3. 03For PoE or isolation, the magnetics decide — not the jack.A jack without magnetics provides neither PoE nor isolation by itself; choose a PoE-rated LAN transformer or a jack with integrated PoE magnetics.See LAN transformers →

07FAQ

SYT111B603EA2A1DFL FAQ

Does SYT111B603EA2A1DFL have integrated magnetics?

Yes. SYT111B603EA2A1DFL integrates the Ethernet magnetics.

Check the datasheet for the rated data rate and whether the magnetics are PoE-rated before using it in a PoE design.

What does Tab Down mean for SYT111B603EA2A1DFL?

Tab Down describes where the latch sits relative to the PCB.

With Tab Up the latch faces away from the board; with Tab Down it faces the board. Choose the orientation that matches your enclosure opening and LED placement, and check the mirrored pinout before swapping one for the other.

How do I get samples of SYT111B603EA2A1DFL?
