I/O Companion Board

The CCA-LAMBADA communicates to the host CPU by means of the expansion connector, which incorporates the LPC and AC’97 interfaces. The LPC (Low Pin Count) is a multiplexed ISA bus, enabling the super-I/O controller chip to emulate the legacy I/O interfaces. Among these are parallel and serial ports, the PS/2 interfaces, and last not least the classic 1.4/2.8MB floppy disk controller. The AC’97 interface is used for control of an
optional audio codec on the CCA-LAMBADA. By connecting the boards together, the hosts ATA/IDE secondary interface is also available on the CCA-LAMBADA. Optionally, the board can be equipped with either a CompactFlash
mezzanine module, or a robust 2.5-inch hard disk drive, particularly suited for use in a rugged environment. A mezzanine module will be also available which carries an 1.8-inch drive, as an alternative.
The CCA-LAMBADA can be mounted either on the left (bottom) side of the CPU board, or right (top) side. Specify your actual needs when ordering the unit. In addition to front panel I/O, some of the interfaces of the CCA-LAMBADA are available for rear I/O across the connectors J1/P1 and J2/P2. A suitable rear I/O transition module such as the CCZ-RIO would be required in addition to gain access to the I/O ports from the systems back panel.
Several I/O functions are also directly available by on-board headers on the CCA, mainly the IDE and FD interfaces. Most of the on-board connectors are only stuffed as an option, however. If equipped with the rear I/O connectors J1/J2, the CCA-LAMBADA must be inserted on a slot outside of the CompactPCI backplane. A single slot rear I/O P1/P2 backplane should be present in the system rack at the CCA reserved slot. Most EKF systems have the CPCI busprint justified to the left margin of the 19-inch rack, with the system slot (CPU slot) orientated to the right end of the backplane. Following next to the right side, the CCA-LAMBADA should be placed in between the remaining free mounting space.
