Description

The T90FJR, also called CIMaX鈩?controller is the hardware extension of SCM Micro-

systems鈥?second generation Common Interface integration package (CI Pack+鈩?. 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鈩?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鈩?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鈩?

CIMaX鈩?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.
