Notes:
1.
Add “R” to the end of the ordering part number to denote tape-and-reel option. E.g., Si3452-B02-GMR.
2.
For alternative A, power is applied to wire pairs 1,2 and 3,6. For alternative B, power is applied to wire pairs 4,5 and 7,8
(the spare pairs in the case of 10/100 Ethernet). Conventionally, alternative B is used for midspan power injectors. For
alternative B, detection is done with over 2 seconds between detection pulses so as to avoid interfering with end-point
equipment trying to provide power using alternative A.
3.
Devices powering up into shutdown mode are intended for use with a system host that provides run-time configuration
or power-management.
4.
The maximum PoE or PoE+ power applies to all ports on Auto mode devices.
5.
Detect Timing and Powerup Modes (PoE vs. PoE+, Shutdown vs. Auto) are pre-configured in firmware but can be
reconfigured at any time via a host connection.
6.
All devices are packaged in RoHS-compliant, 40-pin, 6x6 mm QFN.
7.
The Si3452-B02-GM is PoE+ capable. The part defaults to PoE mode at powerup but can be reconfigured to PoE+ via
register settings.
