SN65LVDS84AQ-Q1: selection of LVDS Serdes

sandeep mir

Part Number: SN65LVDS84AQ-Q1
Other Parts Discussed in Thread: SN65LVDS86A

My application requires <10us latency distribution of a 128-bit signal over 10m of CAT6e. Needs to support 100C .

Based on my browsing I'm planning to use the combination 6 * SN65LVDS84AQ -> SN65LVDS86A .

However the 2009 interface selection guide doesn't seem to list these parts : https://www.newark.com/pdfs/techarticles/ti/InterfaceSelection.pdf

Is there a more recent guide or a better part to use?

I'm concerned about the min input clock frequency of 31 MHz : I would like to sometimes operate at 1.6MHz CLKIN .

Are you looking for an alternative part to the 84A or the 86A?

Hello

Even though this part is not listed in the Interface guide, this part is supported and is available on TI.com webpage. This part will operate to Datasheet specifications of minimum Input clock frequency. Operating at 1.6MHz will not work

Thanks

Hello Vijaya,

We found the part we were looking for (ds90c241) : it seems the national semi parts are not yet integrated into the TI selection guides!

This part supports the 5MHz clock and 12X wire reduction that we need.

Thanks.
