SC9-TOCCATA • CompactPCI® Serial CPU Board • 11th Generation Intel® Processors
Mezzanine Connectors
Three connectors are available for SC9-TOCCATA mezzanine expansion. Two high speed signal
connectors (HSE1, HSE2) and in addition a side band I/F connector (N-EXP) are populated on top
of the CPU board.
EKF offers low profile mezzanine modules which fit into the 4HP envelope of the CPU carrier card,
with varying B2B clearance from 10.0mm to 10.8mm, and also side cards for additional 4HP
mounting pitch (8HP in total assembly, 18.7mm B2B). The female connector N-EXP is identically
populated on carrier and mezzanine and requires a suitable pin header (stacker) as contact
element between carrier and mezzanine in addition. The HSE1/HSE2 connectors of carrier and
mezzanine are female (CPU) and male (mezzanine) pairs, selected to match the individual B2B
height requirements:

The S8* mezzanines are intended to complement the CPU carrier card with respect to the P6
backplane connector, for up to 8 Gigabit Ethernet ports. The SC9-TOCCATA itself does not provide
the P6 connector, according the CompactPCI® Serial Mezzanine Concept.
