EVALUATION BOARD HARDWARE 
POWER SUPPLIES 
When using the EVAL-AD2S1210 with the EVAL-CED1Z, all 
supplies are provided from the controller board through the  
96-way connector. 
When using the EVAL-AD2S1210 board as a standalone unit, 
external supplies must be provided. This evaluation board has 
the following six power supply inputs: 
•  AV
DD
 
•  DV
DD
 
•  V
DRIVE
 
•  +12 V 
•  AGND 
•  DGND 
If the evaluation board is used in standalone mode, 5 V must be 
connected to the AV
DD
 input to supply the 
 AV
DD
 pin. In 
addition, 5 V must be connected to the DV
DD
 input to supply 
DD
 pin, the PI74ALVTC16245AE, and the 
74HC573. To supply the 
 quad op amp, 12 V should be 
used. Lastly, 0 V is connected to one or both of the AGND 
inputs and to the DGND input.  
The AV
DD
, DV
DD
 and V
DRIVE
 supplies are decoupled to the 
relevant ground plane with 4.7 μF tantalum and 0.01 μF multi-
layer ceramic capacitors. Th
, the PI74ALVTC16245AE, 
and the 74HC573 are decoupled to the relevant ground plane 
with 10 μF tantalum and 0.1 μF multilayer ceramic capacitors. 
Extensive ground planes are used on this board to minimize  
the effect of high frequency noise interference. There are two 
ground planes, AGND and DGND. These are connected at one 
location close to the AD2S1210. 
LINK OPTIONS 
There are 16 link options that must be positioned for the required 
operating setup before using the evaluation board. The functions 
of these options are outlined in Table 1.  
Table 1. Link Option Functions 
Link No. 
Function 
LK1 
This link selects the source of the SAMPLE input signal for the AD2S1210. 
 
In Position A, the SAMPLE signal is received from the externally applied SAMPLE signal via the J8 SMB socket or the J20 
connector. 
 
In Position B, the SAMPLE signal is received from the evaluation board controller via the 96-way connector. 
 
In Position C, the SAMPLE signal is received from the S2 push-button switch. 
LK2 
This link selects the source of the CS input signal for the AD2S1210.  
In Position A, the CS signal is received from the externally applied CS signal via the J9 SMB socket.  
In Position B, the CS signal is received from the evaluation board controller via the 96-way connector. 
In Position C, the CS signal is received from the S3 push button switch. 
LK3 
This link selects the source of the RD input signal for the AD2S1210. 
In Position A, the RD signal is received from the externally applied RD signal via the J10 SMB socket. 
In Position B, the RD signal is received from the evaluation board controller via the 96-way connector. 
In Position C, the RD signal is received from the S3 push-button switch. 
LK4 
This link selects the source of the WR/FSYNC input signal for the AD2S1210.  
In Position A, the WR/FSYNC signal is received from the externally applied WR/FSYNC signal via the J11 SMB socket or the J20 
connector. 
In Position B, the  WR/FSYNC signal is received from the evaluation board controller via the 96-way connector. 
LK5 
This link selects the source of the SOE input signal for the AD2S1210. 
 
In Position A, the SOE signal is tied to V
DRIVE
 (parallel mode). 
 
In Position B, the SOE signal is tied to DGND (serial mode). 
LK6 
This link selects the source of the A0 input signal for the AD2S1210. 
In Position A, the A0 signal is received from the externally applied A0 signal via the J15 SMB socket or the J20 connector. 
In Position B, the A0 signal is received from the evaluation board controller via the 96-way connector. 
 
In Position C, the A0 signal is tied to V
DRIVE
.  
 
In Position D, the A0 signal is tied to DGND.  
LK7 
This link selects the source of the A1 input signal for the AD2S1210. 
 
In Position A, the A1 signal is received from the externally applied A0 signal via the J16 SMB socket or the J20 connector. 
 
In Position B, the A1 signal is received from the evaluation board controller via the 96-way connector. 
 
In Position C, the A1 signal is tied to V
DRIVE
 
In Position D, the A1 signal is tied to DGND.
