This section describes the processor's configuration on the EZ-KIT Lite
board.
Figure 3-1. System Architecture Block Diagram
The ADSP-21161N processor's core voltage is 1.8V, and the external
interface voltage is 3.3V.
A 25 MHz through-hole oscillator supplies the input clock to the proces-
sor. Footprints are provided on the board for a surface-mount oscillator
and a through-hole crystal for alternate user-installed clocks. The speed at
