HSMC Expansion Connector
The board provides one HSMC connector. The HSMC connector is a
modified version of standard high-speed Samtec connectors. To provide
better signal integrity between the host boards and daughtercards when
using high-speed transceivers, the standard high-speed Samtec connector
is modified by removing every third pin in bank -1.

CMOS utilization of the HSMC pins is assumed and no options
for supporting other differential signaling is provided with the
board. The eight clock-data-recovery high-speed transceiver
channels are not connected.
lists the ordering codes and shows the relationship between the
standard Samtec Q-series connectors and the modified parts’ ordering
codes.
The board provides both 12 V unregulated and 3.3 V regulated power
supply to the HSMC connector for any installed daughtercards.
