AM3552 - VDDS_DDR and DDR2

Hirotaka Matsumoto

Other Parts Discussed in Thread: TPS65910A

Hi All,

Would you mind if we ask VDDS_DDR and DDR2 on AM3552?

<Question>
VDDS_DDR voltage range : 1.71V(min)～1.89V(max)
Is it possible to use VDDS_DDR or DDR2 with 1.70V?
(Because when we use TPS65910A, the worst case of VDDS_DDR voltage wii be 1.70V.)

Kind regards,

Hirotaka Matsumoto

Hi Matsumoto-san,

The output voltage of the VIO SMPS of TPS65910A is rated at 1.8V +/- 3%, which falls within the required VDDS_DDR input voltage of AM335X, which is 1.8V +/- 5%.
