XM101 Board Technical Description

X-Ref Target - Figure 1-2
The XM101 provides four Samtec QSE family connectors which break out a subset of the
FMC HPC signal set, as shown in
The FMC HPC signals are connected as length matched pairs to the QSE connectors.
XM101 board users may loop back these pairs using the kit Samtec loopback cable, or
create their own unique mezzanine board to plug onto the QSE connectors.
Two Silicon Laboratories Si570 serial IIC bus reprogrammable LVDS clock chips are
available.
The Si570 components are connected to an IIC bus switch. The bus switch component
connects to the main IIC bus implemented in the FMC HPC interface, enabling the board’s
FPGA to program the clock circuitry on the XM101.
A 2-Kb serial IIC EEPROM is also connected to the IIC interface of the board, providing
non-volatile storage.
