Hi Craig,
Do you mean a Power Over Ethernet application where the power to the board is supplied via Ethernet cable (Cat5e)? We have such example application using our 10/100Mbps Ethernet PHY, DP83822I. More information about the POE design can be obtained…
Hi Howard, We also have our bulk cap as 100uF for our PoE Lighting design, TIDA-01463. Using a larger bulk cap is not unusual for a buck topology. There may be a spike of current when you connect the LEDs which can hit the operational current limit…
As you have mentioned there are two families of parts, the 'E' and the 'P'. The 'P' has the higher performance ADC while the 'E' has the integrated MAC & PHY. With regards to the POE, there are a couple of reference designs, one with the 'E' device…
Hi Sandesh,
We do not have an exact RMII reference design for connection to a microcontroller.
The closest reference design to fit your requirement is the LED lighting design. www.ti.com/.../TIDA-01463
This can be re-purposed by strapping the…
Sylvain,
The TI Reference design TIDA-01463 (Connected LED Lighting With IEEE802.3bt Power Over Ethernet (PoE) Reference Design ) that has a UDP example you coudl use for this purpose. Look down the page in the software tools section (linked). Once you…
Hi User,
EEE is a mode that is part of the data side. The data packets will be sent more efficiently that saves overall power at standby modes. For example, in poe lighting like shown below, when LED ballast is OFF, the overall power consumption meets…
