Preliminary data sheet
10.15 Power and grounding
In order to obtain optimum performance, it is recommended that the 1.8 V analog power
supplies on pins 5, 11, 71, 77 and 99 should not be connected with the ones on pins 6, 70,
79, 81, 83, 93, 95 and 97 on the top layer.
To optimize the decoupling, the power supplies should be decoupled with the following
ground pins:
