Problem with some components #7
Description
Hello,
I have been exploring the schematic for a while now, and I have noticed some problem with some components.
The EEPROM 93C46B-I_SN
on the USB block, U22 seems to be fed with a 3V3 power supply.
However after consulting the datasheet for this component, it seems that it only tolerate 4.5 to 5 V power supply :
I would suggest to go with 93LC46B-I_SN since it has the same footprint and the same function, and can be supplied with 3.3V
The programmable clock generator Si5351A-B-GT
On the white rabbit block the clock generator is associated with an oscillator XTAL_25MHZ_TXC_8Y-25.000MAAJ-T, which has a load capacitance of 18pF.
However according to the datasheet, the clock generator as internal load capacitance that can go up to 10pF with optional external capacitance that can go up to 2pF making the total tolerated load capacitance of maximum 12pF.
The application note AN551 is giving some recommendation to select the external crystal oscillator :
I would suggest a kyocera CX3225SB25000D0FLJCC since it's also 25Mhz but with a 8pF load capacitance.
