Part Number: SN65LVDS93A

If Hsync and Vsync are input to the SN65LVDS93A as Low Active, are the polarity of Hsync and Vsync in the LVDS Data Low Active?
If not, can it be set to Low Active?

Do the TTL input Hsync and Vsync inputs of the SN65LVDS93A have to be High Active signals?

Hello,

It does not appear that the SN65LVDS93A is capable of changing the polarity of HSYNC and VSYNC. More specifically, this device is a pass-through parallel to serial LVDS, meaning that low input will correspond with low output and high input will correspond with high output.

Whether low active or high active is needed for HSYNC and VSYNC will be based on the particular needs of the specific display in the system.

Best,

Nikolas

Is the SN65LVDS93A Spec to input Active High Hsync and Vsync?

Hello,

There is no particular spec - the SN65LVDS93A can accept either active high or low input HSYNC or VSYNC. Whether its high or low will depend on the incoming video data.

Best,

HSYNC/VSYNC of LVDS OUT is Active High even when Input Hsync/Vsync Active High or Input Hsync/Vsync Active Low.
Is this understanding correct?

Hello,

No - the SN65LVDS93A appears to be a passthrough device, meaning that whatever state is inputted will be passed through to the output.

Low Active Input --> Low Active Output

High Active Input --> High Active Output
