72 Pin/48 Pin Package Options
The KAD5512HP is available in both 72 pin and 48 pin
packages. The 48 pin package option supports LVDS DDR
only. A reduced set of pin selectable functions are available
in the 48 pin package due to the reduced pinout;
(OUTMODE, OUTFMT, and CLKDIV pins are not available).
Table 17 shows the default state for these functions for the
48 pin package. Note that these functions are available
through the SPI, allowing a user to set these modes as they
desire, offering the same flexibility as the 72 pin package
