Zynq ADC pin selection

Hello!

I need to design zynq-7000 based board to get some functionality including 12 ADC channels.

First of all I read this:

http://zedboard.org/content/zynq-pins-deep-dive

There is explained that I need:

1) determine used chip - xc7z020clg400

2) open corresponding pinout file:

http://www.xilinx.com/support/packagefiles/zynq7000-pkgs.htm

3) select pins which has AD#P/N in their names.

If I don't need differential mode do I need only one pin (P or N) from 

every XADC pins pair?

For example:

C20  IO_L1P_T0_AD0P_35
B19 IO_L2P_T0_AD8P_35
E17 IO_L3P_T0_DQS_AD1P_35
E18 IO_L5P_T0_AD9P_35
M19 IO_L7P_T1_AD2P_35
M17 IO_L8P_T1_AD10P_35
L19 IO_L9P_T1_DQS_AD3P_35
K19 IO_L10P_T1_AD11P_35
J18 IO_L14P_T2_AD4P_SRCC_35
F19 IO_L15P_T2_DQS_AD12P_35
J20 IO_L17P_T2_AD5P_35
G19 IO_L18P_T2_AD13P_35

Re: Zynq ADC pin selection

Hi,

 

Users can optionally configure the external analog input channels to operate in unipolar or bipolar modes.

Refer to Analog Input section in page 28 of http://www.xilinx.com/support/documentation/user_guides/ug480_7Series_XADC.pdf.

Praveen
