7 High Speed Mezzanine Card (HSMC) Connector

The connector used in HSMC applications is a custom version of the 0.5mm-pitch QTH-DP
and mating QSH-DP series from Samtec, Inc. There are three "banks" in this connector. Bank
1 will have every third pin removed as is done in the QSH-DP/QTH-DP series. Bank 2 and
Bank 3 have all of the pins populated as done in the QSH/QTH series. The default mating
connector is the ASP-122952-02. The ASP-122952-01 connector can plug directly into hosts
with QSH-060-01-L-D-DP or QSH-060-01-L-D connectors with the –DP version having slightly
better signal integrity.

7.1 HSMC Connector Pin out Table

Table 4 shows for every pin of the HSMC connector on the board and the corresponding PHY
signal. The signal suffix "_0" indicates PHY1 and "_1" indicates PHY2. Unused pins are left blank.
