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 host boards and daughter cards 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.
Table 2–6 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 daughter cards.

For more information regarding the HSMC, refer to the High Speed
Mezzanine Card Electrical and Mechanical Specification version 1.2 or later.
Table 2–7 lists the guaranteed minimum on-board power supply levels.
The power rails are delivered via designated pins on the HSMC
connector.
