Part Number: 66AK2H14

HI,

There are 2 DDR3 interfaces in the 66AK2H14, which look independent.

My question is relative to the DDR3AVrefSSTL and DDR3BVrefSSTLinput pins :

Can their voltage be set by different parts, or should they be both connected to the same single DVDD15%2 voltage ?

With best regards,

Bruno

Hi Bruno,

Check the K2H EVM schematics, you will see that DDR3AVrefSSTL and DDR3B VrefSSTL input pins are connected to two SEPARATE TPS51200DRCT devices (marked U60 and U38 respectively).

Best Regards,
Yordan
