Pin Descriptions
Description
DACVCC should be isolated from all other
VCCs, and should not be greater than
CORVCC.
DACGND should be common with digital
ground but must be tightly coupled to
DACVCC.
MCKVCC and DCKVCC must be at the
same voltage level as CORVCC.
Each of the MCKVCC/MCKGND and
DCKVCC/DCKGND pairs must be
INDIVIDUALLY decoupled.
Balls D5 and C4 (DCKVCC) may be
jumpered together. Balls B4 and A3
(DCKGND) may be jumpered together
Refer to the section on clock generation for
suggested clock power and ground PCB
layout.
