A/T90FJR
Generator (UCSG)maps CPU control bus into Command Interface control signals. To minimize
pin count, host address and data buses transit through external buffers that are driven by
CIMaX.
CIMaX includes a memory mode that allows to use any of the two Common interface slots to
read/write a 8-bit PC Card Memory card. This feature gives the receiver memory extension
capability for software upgrade or better performance.
In case of modules order is significant, CIMaX may virtually swap them (SCM’ Patent Pend-
ing) after identifying which module must be in front of the transport stream.
CI Pack+ includes hardware, software and qualification tools and is suitable for Set Top box,
Digital TV set or PC board.
