AM625: DDR4 VTT Termination Resistor Value

Part Number: AM625

Hi Team,

My customer has the following question about DDR4 design.

If they use 2 8-bit DDR4s it should be designed as prescribed in SPRAD06 document Fig.2-2 (VTT termination required)

Is there any recommended value for the termination resistor on the AM625 side? If not they plan on using the DDR4 maker recommended value. (33~39Ω)

Best regards,

Mari Tsunoda
