4.8.4. HSMC

The high-speed mezzanine card (HSMC) interface is based on the Samtec 0.5 mm pitch, surface-mount QTH/QSH family of connectors. It is designed to support a full SPI-4.2 interface (17 LVDS channels) and 3 input and output clocks as well as SMBus and JTAG signals.

Since MAX 10 does not have transceiver channels, the HSMC clock-data-recovery channels are left unconnected.

The HSMC interface has programmable bi-directional I/O pins that can be used as 2.5-V LVCMOS, which is 3.3-V LVTTL-compatible. These pins can also be used as various differential I/O standards including, but not limited to, LVDS, mini-LVDS, and RSDS with up to 17 full-duplex channels.

As noted in the High Speed Mezzanine Card (HSMC) Specification manual, LVDS and single-ended I/O standards are only guaranteed to function when mixed according to either the generic single-ended pin-out or generic differential pin-out.

For more information about the HSMC specification such as signaling standards, signal integrity, compatible connectors, and mechanical information, refer to the High Speed Mezzanine Card (HSMC) Specification manual.
