Figure 8. KLAS Board 43mm x 18mm
Per the SMARC specification, the Module LVDS path is single-channel LVDS only. The physical interface is capable of 18
bit (4 LVDS pair) and 24 bit (5 LVDS pair) color depths. Per the SMARC specification, the Module must support 18 bit
single channel LVDS, should support 24 bit single channel LVDS in the 18 bit compatible LVDS format, and may
support 24 bit single channel LVDS in the 24 bit standard LVDS format. (There is a more detailed discussion of the LVDS
formats in the SMARC specification document). The most common Module LVDS format will be 18 bit single channel
LVDS.
The connectors used for the KLAS Mezzanine to Evaluation Carrier are:
Vendor Vendor P/N Where Used Kontron PN
Hirose FX12B-60S-SV SMARC Evaluation Carrier 1052-2683
Hirose FX12B-60P-SV KLAS Mezzanine PCB 1052-2681
These connectors are fine pitch (0.4mm) low profile (1.5mm board to board) parts with excellent signal integrity
characteristics. The connector vendor claims operation to 6 GHz and beyond.
The SMARC Evaluation Carrier has no parts, other than the Hirose FX12 connector and mounting standoffs, in the
shadow of the 43mm x 18mm KLAS board. The KLAS boards may thus have parts on the bottom side, up to 1.3mm tall.
Top side KLAS part height should be limited to 3mm.
