[NCG][MIC-6315] on board DDR4 ( Samsung ) DDR_VREF Voltage problem.

[BLan]

MIC-6315 DDR4 Circuit diagram, The DDR_VREFCAB reference voltage ripple is too large (R204 and R206 DDR_VREFCAB ripple 30~50mV), so I use U137 pin6 (output VTTREF) when DDR_VREFCAB reference voltage, I want to ask, I use TPS51200 PIN 6 when DDR_VREFCAB reference voltage Is it feasible?
