Hi Everyone,
I.
If I have a surface mount device (VCSEL Driver) that has a supply voltage of 2.5V and the datasheet states that the supply should not have more than +/- 400 mV peak to peak (200 mV peak) how can I or what can I do to make sure I meet this requirement?
Do I place a cap to GND? If so what value?
The supply current is a maximum 0.6 mA. Yes milliamperes.
II.
If I have a device (TIA) that uses dual supplies, 2.5V and 1.2V, what is the best way to get 1.2V from a 2.5V source? Do i just use a voltage divider (resistors)? or does this not help me meet a noise spec of 200 mV peak to peak (100 mV peak).
Thank you.
