DDR4 JEDEC of TPS51200

Other Parts Discussed in Thread: TPS51200

I have a question about TPS51200.

We asked you about DDR4 JEDEC.

TPS51200 is not fully compliant with DDR4 JEDEC

    In DDR4 JEDEC, Vref must track VDDQ/2, and it must be within +/-300mV with respect to VDDQ/2 during power up.

We recieved the attached document from our customer. But we cannot find this sentense.

Best regards,
