Hi,
You can check the de-serializer d/a, which has coax description, such as DS90UB948, ds90ub940, etc.

regards,
Steven

Hi Steven:
As your say,the DS90UB947 can use coaxial cable with DS90UB948.Can you provide coaxial cable designed assistance?
Only differential cable designed we found in TI.COM.Can you provide an coaxial cable schematic design for us that we can reference.

Hi,

the design should be very similar but you need to setup the Mode pins (Mode_SEL) accordingly.
Also in the UB947 Datasheet you have a coax schematics example on page 67.
