Available as a mezzanine add-on companion
board to the CCG-RUMBA card, the
CCJ-RHYTHM enables the CCG-RUMBA to act as
a system slot CPU simultaneously for both a
CompactPCI backplane, and in addition a
CompactPCI Express backplane. In order to
simplify system integration, suitable all-in-one
(heterogeneous) backplanes are available from
independent vendors, which allow insertion of
classic CPCI I/O boards (left from CCG-RUMBA)
as well as high speed CPCIe cards (right to CCJRHYTHM). The user profits from such a hybrid
solution by combining low cost CPCI modules,
available from numerous vendors, with the
advanced features of CPCIe boards in a single
system, thus providing maximum flexibility.
The CCJ-RHYTHM will be attached on top of the
CPU board, and shares its front panel typically
with the host carrier (8HP front panel width in
total). Interconnection between the CCJRHYTHM I/O module and the CPU carrier board
is achieved by several expansion connectors,
which comprise the PCIe (PCI Express), LPC (Low
Pin Count), PATA/IDE and SDVO interfaces
The heart of the CCJ-RHYTHM is a 6-port 24-
lane PCIe packet switch. One port is used as a
link to the PCIe host (which is the ICH8M-E on a
CCG-RUMBA). Four ports establish the
CompactPCI Express system slot interface (4-link
configuration pin assignments). The remaining
port is used locally by a IEEE1394 bridge.
In addition to its CPCIe system slot function, the
CCJ-RHYTHM is provided with high-speed
communication channels such as FireWire and
USB, and common legacy I/O ports as well
(COM, LPT). Optionally, a DVI connector allows
for dual screen video operating mode.
As an option, the CCJ-RHYTHM is available with
a rugged on-board 2.5-inch PATA hard disk (or
even Flash) drive. Alternatively, either a
CompactFlash card adapter, or an 1.8-inch hard
disk can be accommodated, as a mezzanine
module, and in addition an USB Solid-State Disk
(SSD) module. Another option available is the
Trusted Platform Module according to TPM 1.2
for safety critical applications.
