Expansion Interface Ii - Analog Devices EZ-Board ADSP-BF518F Manual

Expansion Interface II

The expansion interface II allows an Analog Devices EZ-Extender or a
custom-design daughter board to be tested across various hardware plat-
forms that have the same expansion interface.
The expansion interface II implemented on the ADSP-BF518F EZ-Board
consists of four connectors, three of which are 0.1 in. shrouded headers
( ), and the last of which is a Samtec QMS series header (
P2—4
nectors contain a majority of the ADSP-BF518F processor signals. For
pinout information, go to

Limits to current and interface speed must be taken into consideration
when using the expansion interface II. Current for the expansion
interface II is sourced from the EZ-Board; therefore, the current should be
limited to 1A for 5V and 500 mA for the 3.3V planes. If more current is
required, then a separate power connector and a regulator must be
designed on a daughter card. Additional circuitry can add extra loading to
signals, decreasing their maximum effective speed.
Analog Devices does not support and is not responsible for the
effects of additional circuitry.
