ADV7180->ADV212 Series Termination Resistors Needed?

Do I need series termination resistors (33 ohm for example) on the data and LLC clock lines between an ADV7180 and the VDATA input port on an ADV212?  I've only used the ADV7180 previously with an Altera FPGA, and on the Altera, I turned on the Rs series resistors in the I/O blocks that the ADV7180 and ADV7171 were connected to.

 

I'll be running 8 bit data at 27MHz between the parts, with embedded sync, so just the 8 data lines plus the LLC output from the NTSC decoder.

 

Thanks!
