6.2 EMAFE Expansion
WARNING:
Using the EMAFE interface connector to connect to a MAFE board can damage the
ADSP-21065L EZ-KIT Lite, the MAFE, or both.
This section describes the Enhanced Modular Analog Front End (EMAFE) Daughter Card interface for the
ADSP-21065L digital signal processor evaluation board. The EMAFE interface includes additional signal
definitions for the I
2
S capabilities of the ADSP-21065L processor. The EMAFE allows an upgrade path
for evaluating present and future codec's and ADC's (18xx, AD7xxx, multimedia codec, etc.) with the
ADSP-21065L evaluation board. Only the analog front end will be placed on a daughter board. Each
EMAFE daughter board will have its own back plate to allow different input connections (i.e. RCA jack,
Mic in, speaker out, etc.). The daughter board is attached to the ADSP-21065L evaluation board by a
single 96 pin right angle mounted male connector and two mechanical standoffs to give stability to the
entire arrangement when the daughter board and evaluation board are attached. The evaluation board has a
96 pin right angle mounted female connector. The signal lines that need to be routed to the EMAFE
daughter board from the evaluation board should be kept to a minimum to reduce noise. Signals routed to
the EMAFE daughter board from the ADSP-21065L evaluation board are defined below. Please note,
Analog Devices does not provide a daughter board, the user must design this board.
