Functional Description
SFP Control
- Input Signal LA03_N sets all four SFP RX modes (LA03_N=HIGH sets RS0 signals LOW for 1000BASE-SX, LA03_N=LOW sets RS0 signals HIGH for 10GBASE-SR)1
- Input Signal LA04_P sets all four SFP TX modes (LA04_P=HIGH sets RS1 signals LOW for 1000BASE-SX, LA04_P=LOW sets RS1 signals HIGH for 10GBASE-SR)1
- Output Signals LA05_N, LA06_N, LA07_N and LA08_N indicate signal loss of SFP A, B, C and D respectively (HIGH indicates signal loss).
- Output Signals LA05_P, LA06_P, LA07_P and LA08and LA08_P indicate SFP A, B, C and D module absend absent (HIGH when module physically absent).
- Output Signal LA04_N is HIGH when at least one of the four SFPs indicate Laser fault.
- Input LA03_P HIGH sets for all SFPs where the module is physically available (MDEF0_i is LOW) the TX_DIS signal to LOW.2
1SFP Control and I2C register writes of RX/TX modes are couppled with a logical or. If at least one of them indicates HIGH the 10GBASE-SR is activated.

12Inverted control as we can not enable weak pulldown in MAX10, we use weak pullup. E.g. TX are all ENABLED at default power up, so the card is working with no FMC LA pin driven.
...
- LA00_P, LA00_N and LA01_P form a "three wire I2C" bus with seperate separate data in and output.
- LA01_N, LA02_P and LA02_N are used as selector for the MUX.
