Altera Santa Cruz - Manual (Page 5)

© December 2008 Altera Corporation Santa Cruz, USB, MICTOR, SD Card HSMC Reference Manual
1. Overview
General Description
This manual provides information about the THDB-SUM, an adapter board that
converts High-Speed Mezzanine Card (HSMC) interface to Santa Cruz, USB,
MICTOR, and secure digital (SD) card interfaces. It allows you to use these interfaces
on a host board with an HSMC connector.
The THDB-SUM provides a set of commonly used interfaces on Altera's newest
generation of development boards. On older boards, the standard “daughtercard”
expansion was through the “Santa Cruz connector.” The THDB-SUM provides this set
of interfaces so that legacy Santa Cruz daughtercards can still be used.
This manual describes each of the hardware interfaces on the THDB-SUM board.
