Description
The T90FJR, also called CIMaX
controller is the hardware extension of SCM Micro-
systems
’
second generation Common Interface integration package (CI Pack+
). It
enables CI Driver software to directly address two complete independent Common
Interface modules.
As such, it contributes to offer an optimized, homogeneous and complete solution for
digital TV receiver manufacturer that wants quickly to implement the Common
Interface.
CIMaX
includes the necessary I/Os to interface the MPEG Transport stream gener-
ated by the receiver demodulator and to daisy chain it through two modules and back
it to the demultiplexer. Voltage level translators allow to avoid any additional
component.
CIMaX
interfaces with major digital TV receiver microprocessors. An I2C bus is
used for initialization and module selection, while a Universal Control Signal Genera-
tor (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 inter-
face 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.
