[Rev0_2] PoE Power does not work

Solution

Change the RJ45 Connector to ARJM11C7-114-BA-EW2. This connector does not have internal rectifier and is also used in sinara-hw Thermostat.…

R8 parallel capacitor

Doing a spice simulation on the circuit shows that this capacitor passes through high frequency components more than without. I think that should not be included. I do not know the original…

[TEST] Testing PD monitor

Maybe but the requirement isn't high and we can probably find a IC that is cheaper and/or already used on other Sinara boards.

TL082 is used in Driver

Okay. Will look into other options later.

Looks like a pretty old and niche part without exceptional performance. Any particular reason why you picked that one?

OPA381 has lower input offset current and input offset voltage than the…

I looked through different types of laser driver(LD) and concluded that the integrated photodiode(PD) capacitance can have a maximum 20pF. But, not all manufactures or types of LDs have their…

TLV2172, Dual Channel CMOS Amplifier should be a reasonable opamp that we are looking for. (Cost a HKD10.52 per pcs at 100 order quantity)

[TEST] Testing PD monitor

I saw that at the end of the AFE front end, there is a LPF with a 1.5923566879kHz cutoff frequency, which should be the contributing factor to the low bandwidth and R100 output resistor. They…
