FMC Connector
The development board contains a high pin count (HPC) FPGA mezzanine card
(FMC) connector that functions with a quadrature amplitude modulation (QAM)
digital-to-analog converter (DAC) FMC module or daughter card. This pinout
satisfies a QAM DAC that requires 58 LVDS data output pairs, one LVDS input clock
pair, and three low-voltage differential signaling (LVDS) control pairs from the
Arria V. These pins also have the option to be used as single-ended I/O pins. The
VCCIO supply for the FMC A banks in the low pin count (LPC) and HPC provide a
variable voltage of 1.5 V, 1.8 V, 2.5 V (default), or 3.3 V. The VCCIO supply for the
FMC B bank in the HPC provides a variable voltage from 1.2 V to 3.3 V, which can be
supplied by the FMC module. However, for the sake of device safety concerns, a
jumper is available for you to connect this bank to the same VCCIO used for the FMC
A banks. This allows the VCCIO pins on the FPGA to be tied to a known power. The
VCCIO pins also allows you the option to perform a manual check for the module’s
input voltage before connecting to the FPGA. This is to ensure that the module does
not exceed the power supply maximum voltage rating.
Table 2–50 lists the FMC connector pin assignments, signal names, and functions.
