Components and Interfaces
Altera Corporation
Stratix III 3SL150 Development Board
lists the Ethernet PHY component reference and manufacturing
information.
High-Speed Mezzanine Cards
The board contains two HSMC interfaces called Port A and Port B. These HSMC
interfaces support both single-ended and differential signaling. The connector part
number is Samtec ASP-122953-01. The HSMC interface also allows for JTAG, SMBus,
clock outputs and inputs, as well as power for compatible HSMCs.
The HSMC is an Altera-developed specification, which allows users to expand the
functionality of the development board through the addition of daughter cards
(HSMCs).
