DEMO MANUAL DC2512A
HSMC Adapter for DC718-
Compatible Demo Boards
DESCRIPTION
Demonstration circuit 2512A is a gasket adapter board that
allows DC718-compatible data converter eval boards to
interface with FPGA boards that have an HSMC connec-
tor, such as the SoCkit Cyclone 5 SoC development board
from Arrow Electronics.
SET TO 3.3V UNLESS OTHER
VOLTAGE IS SPECIFIED

QUICK START PROCEDURE
DC2512A was designed to mate to the Arrow SoCkit board.
DC2512A may work with other HSMC-compatible FPGA
boards, but the pin connections and voltages should be
verified.
Carefully mate the HSMC connector on the reverse side of
the DC2512A to the SoCkit board. Use high-quality, 5mm
spacers such as Harwin R30-6200514, and M3 × 12 or
4-40 × 1/2" pan-head screws.
Most FPGA loads intended for use with the DC2512A
require 3.3V I/O voltage. Unless the test script or other
experiment documentation indicates otherwise, set the
SoCkit’s I/O voltage to 3.3V by placing the JP2 jumper
on the SoCkit board in the 3.3V position (closest to the
edge of the board). Mate the ADC demo board to J1 on
DC2512A. Observe proper power-sequencing: the best
practice is to power up the SoCkit before applying power
to the ADC demo board.
A complete example of a typical evaluation setup is covered
in the blog, “Data Converter Evaluation with the Arrow /
Altera SoCkit FPGA board”:
