EVAL-AD7765EBZ_15 Datasheet, PDF (4/23 Pages) Analog Devices – Evaluation Board for AD7764/AD7765 using

EVAL-AD7764/AD7765EDZ
Preliminary Technical Data
LINK OPTIONS
The link options on the evaluation board should be set for the required operating setup before using the board. The functions of these
links are described in Table 1.
Table 1. Link Options
Link No.
Function
R8, R29, R11
A 0 Ω link must be placed in
either pair of resistors, R11,
R29, or R8 to select the
MCLK source for the
AD7764/AD7765 device.
R15, R16,
R17, R33,
R34, R35,
R36, R37
A 0 Ω link must be placed in
all of these resistors
placeholders to link the
digital outputs of the
AD7764/5 to the EVAL-
CED1Z board.
Position Descriptions
R11routes the MCLK frequency from the EVAL-CED1Z board to the MCLK pin of
the AD7764/AD7765 device. This is the default
R29 or R8 allows the user to input an external MCLK signal through the MCLK
SMB connector (J17) or connect to the 40MHz Crystal oscillator for use in stand-
alone mode.
Place a 0 Ω link in all of these positions.
Default
R11
All shorted
with 0 Ω
links.
