Board Components and Interfaces

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.

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 daughtercards.

f For more information about the HSMC, refer to the High Speed Mezzanine

Card (HSMC) Specification.

Table 2–7 lists the guaranteed minimum on-board power supply levels.

Designated pins on the HSMC connector deliver the power rails.
