Dear Team,

do you have a redriver, retimer, buffer or a similar IC for Sony Low voltage LVDS ( subLVDS)?

Vcm=0.9V

Vod = 150mV

Hi,

You can use a regular LVDS driver coupled with a resistor step down network as detailed here:

We don't have any sub-LVDS devices/transceivers.

Hi Malcom,

we have on both sides LVDS and i want to add in-between a LVDS redriver or buffer.

do you have such a device? both the input and output of the buffer needs to be differential.

Hi d,

I'm adding HSD on this thread because I think their devices might be better equipped to handle your solution than anything we have under logic.

Best,

Malcolm

What is the data rate requirement? Please see this link for a list of LVDS buffer or repeater that we have, https://www.ti.com/interface/lvds-m-lvds-pecl/products.html#404=Buffer%3BRepeater&.

Thanks

Hi David,

Data rate is 600Mbps . i was looking for small solution size. either 5ch in one package or single channel package.

I found those to are the smallest solution if i'm not wrong.

Can you tell the difference between DS25BR150 and DS38EP100 ?

Best Regards,

Hi Malcolm,DS38EP100 is a passive equalizer while DS25BR150 is an active buffer,

Typically we have 4 channels in one package - 5 channels in one package is not what i am aware of.

Please consider DS25CP104A and DS25BR101. These are four and one channel parts. Additionally there is some level of equalization if needed. Please below note link to these two parts data sheet:
