Hello,
I have some questions about LVDS SYNC input as follows.
Q1:
Datasheet 7.3.10.4 says “LVDS works to 250 mVpp, but is not ensured in production.”.
I do not understand this well.
For SYNC input pin, how much LVDS differential amplitude (Vpp) is required at minimum?
Q2:
In Datasheet Figure 31, how much ohm is the resistance?
This should be an usual 100ohms LVDS termination?
Q3:
For LVDS SYNC input, INPIN_HYST should be enabled or disabled?
How to decide disable or enable?
Q4:
LVDS input Vcm could be what voltage range?
Could it be 0.2V to 2.2V like usual LVDS?
Q5:
SYNC pulse width could be more than one OSCin cycle?
For example, after SYNC gets high with enough tSETUP/tHOLD to OSCin rising edge, SYNC can stay high for multiple cycle of OSCin period or forever? Or SYNC must be one OSCin cycle pulse?
Best regards,
