ADSP-21xx Interface
Figure 25 shows the interface between the ADF4113HV and the
ADSP-21xx digital signal processor. The ADF4113HV needs a
24-bit serial word for each latch write. The easiest way to
accomplish this using the ADSP-21xx family is to use the auto
buffered transmit mode of operation with alternate framing.
This provides a means for transmitting an entire block of serial
data before an interrupt is generated.
Set up the word length for eight bits and use three memory
locations for each 24-bit word. To program each 24-bit latch,
store the three 8-bit bytes, enable the auto buffered mode, and
then write to the transmit register of the DSP. This last opera-
tion initiates the autobuffer transfer.

PCB DESIGN GUIDELINES FOR CHIP SCALE
PACKAGE
The lands on the chip scale package (CP-20-1) are rectangular.
The printed circuit board pad for these should be 0.1 mm
longer than the package land length, and 0.05 mm wider than
the package land width. The land should be centered on the pad
to ensure that the solder joint size is maximized.
The bottom of the chip scale package has a central thermal pad.
The thermal pad on the printed circuit board should be at least
as large as this exposed pad. On the printed circuit board, provide
a clearance of at least 0.25 mm between the thermal pad and the
inner edges of the pad pattern. This ensures that shorting is
avoided.
Thermal vias can be used on the printed circuit board thermal
pad to improve thermal performance of the package. If vias are
used, they should be incorporated in the thermal pad at a 1.2 mm
pitch grid. The via diameter should be between 0.3 mm and
0.33 mm, and the via barrel should be plated with 1 oz. copper
to plug the via.
The user should connect the printed circuit board thermal pad
to AGND.
