Is the ADV7842 IBIS model available?
I need to know the ADV7842 SDRAM controller output driver impedance.
(I want to see if I can eliminate the series resistors between the ADV7842 and the DDR SDRAM.)
please check this link
Does the ADV7842 SDRAM Controller control the external DDR SDRAM's data pin drive strength?
I want the external DDR SDRAM data pins to use reduced drive strength.
There is no direct control of DDR pin drive strengths. We normally use series resistors for impedance matching.
Also note that the external memory is only needed for NTSC/PAL 3D Comb filter and TBC functions. If you don't need these then you don't even have to install the external memory.
OK, thanks GuenterL.
