AM3354: Voltage divider query at DDR_VREF

Part Number: AM3354

Hi Experts,

Good day.

May we ask what is the maximum value of voltage divider network (VDDS_DDR into-half) found on page 172,  figure 7-48 of this AM3354 datasheet? Currently they 're both at 1kOhm.

Hoping for your guidance.

Thank you!

Archie A.

  • Having a stable VREF is imperative for proper operation, and keeping a fairly low resistance in the voltage divider helps to ensure this.  1Kohm is recommended.  If you have to raise it, i would not go above 2.2Kohms
