PGP/ETH
- This SFP interface is the PGP or ETH (depending on which firmware is loaded)
- When ETH firmware is load, the carrier board Ethernet PHY is 1000BASE-SX
- The total power draw on the +12VDC is about 10W (+12VDC @ 0.8 A)
- Carrier Board is ~5W
- Digital Daughter board is ~5W
- To prevent the boards from overheating, we require cool air to be blown from a fan
- Using a thermal electric cool on the ASIC would be an acceptable thermal management solution as well
