1.Introduction
The Numato Lab FMC+ HSPC Loopback Module is designed for testing and validating high-speed signal connectivity between an FMC+ compatible FPGA carrier board and the module. The module provides direct loopback paths for the FMC+ interface signals, enabling convenient testing of FPGA I/O and high-speed transceiver interfaces without requiring external signal connections.
The module is compliant with the ANSI/VITA 57.4 FMC+ standard and uses an FMC+ HSPC connector to provide access to the available LA, HA, HB, and high-speed transceiver DP signals. It supports 34 LA differential pairs, 23 HA differential pairs, 22 HB differential pairs, and 48 high-speed transceiver DP pairs.
An on-board programmable Si5332A-GM2 clock generator provides up to eight clock outputs, with a default frequency of 100 MHz on all outputs. An I2C EEPROM is also provided on the module for storing configuration information.
