ADC and Mixed-Signal HSC Interface
The Blackfin EZ-Extender can connect to an analog-to-digital converter
(ADCs) and a mixed-signal HSC evaluation board via the
ADC/mixed-signal HSC interface. The ADC/mixed-signal HSC interface
consists of a 40-pin female header, which contains all of the control and
data signals necessary to transfer data between the processor’s parallel
peripheral interface (PPI) and the HSC evaluation board. Additionally,
the extender provides a RJ-45 connector, which contains all of the serial
peripheral interconnect (SPI) signals necessary to configure the control
registers of capable HSC converters. For a block diagram of this interface,

Before using the Blackfin EZ-Extender, familiarize yourself with the docu-
mentation and schematics of the target board and the EZ-KIT Lite. For
example, on the EZ-KIT Lite, it may be necessary to disable other devices
on the PPI, route the PPI clocks, and disable the push buttons.
