How to Choose an Industrial PCB RJ45 Jack: Seven Constraints That Decide the Part

How to Choose an Industrial PCB RJ45 Jack: Seven Constraints That Decide the Part

Choosing an industrial PCB RJ45 jack starts from the constraint the application imposes, not from the application name. Seven constraints decide most choices: vibration and cable retention, sealing and condensation, shielding and grounding, panel space, P

EtherCAT PHY Requirements: What an EtherCAT Slave Needs from Its PHY

EtherCAT PHY Requirements: What an EtherCAT Slave Needs from Its PHY

An EtherCAT slave needs a PHY that runs IEEE 802.3 100BASE-TX (or 100BASE-FX) at 100 Mbit/s full duplex and connects to the EtherCAT slave controller (ESC), preferably over MII. Beckhoff's PHY selection guide lists the must-haves: auto-negotiation, MDI/MD

PoE PSE vs PD: What Each End Does and Which Magnetics It Needs

PoE PSE vs PD: What Each End Does and Which Magnetics It Needs

In Power over Ethernet (PoE), the PSE (power sourcing equipment) is the end that supplies power, such as a PoE switch port or a midspan injector, and the PD (powered device) is the end that receives it, such as an IP camera, a wireless access point or an

Push-Pull vs Flyback Converter: Which Isolated Topology Should You Choose?

Push-Pull vs Flyback Converter: Which Isolated Topology Should You Choose?

Choose a push-pull converter when the input is a fixed low-voltage rail and you need a simple isolated bias supply, for example for an isolated RS-485, CAN or SPI interface. A driver such as TI's SN6501 switches a center-tapped transformer from a 3.3 V or

Ethernet Magnetics PCB Layout: Should There Be a Ground Plane Under the Magnetics?

Ethernet Magnetics PCB Layout: Should There Be a Ground Plane Under the Magnetics?

Not directly under the magnetics. In an Ethernet magnetics layout, keep a continuous ground plane under the MDI traces from the PHY to the transformer, then void it under the discrete transformer and the other parts on those traces. TI's Ethernet PHY PCB

What Is QSGMII? QSGMII vs SGMII and USXGMII for Multi-Port PHYs

What Is QSGMII? QSGMII vs SGMII and USXGMII for Multi-Port PHYs

QSGMII (Quad Serial Gigabit Media Independent Interface) is a MAC-to-PHY interface that combines four SGMII ports into a single 5 Gb/s serial link, so one SerDes lane in each direction carries four 10/100/1000 Mbit/s Ethernet ports. It is used between a m

USB ESD Protection: How to Choose ESD Diodes for USB 2.0 and Type-C Ports

USB ESD Protection: How to Choose ESD Diodes for USB 2.0 and Type-C Ports

USB ESD protection means placing an ESD diode on every line that leaves the board through the USB connector, as close to the connector as the layout allows, so that a discharge is diverted to ground before it reaches the USB controller. For the USB 2.0 da
