Tool/software:
Dear HSC team,
My customer is currently investigating a SerDes topology in their design to reduce inter-board signals between PCBAs. They are targeting the DS92LV1x component, and their source signals are mainly binary without heavy timing constraints.
Their design includes UART communication between PCBAs. They would like to estimate if they can embed UART communication within their LVDS link provided by the SerDes between our PCBAs. If yes, what is the maximal speed of UART versus TCK and REFCK of the DS92LV1x component?
To clarify my question, here is a simple text schematic:
UART PCBA #1: RX <- <- TX
TX -> [DS92LV1x] 
[DS92LV1x] -> RX : UART PCBA #2
Is this possible? What is the maximal speed of UART I can achieve for a 50 MHz SerDes clock?
By the way is see that the DS92LV1x is pretty old, has it been migrated to RFAB ? And do we have newer devices similar to promote instead ?
Thank you for your help and support .
Thanks,
Flo
