CableCARDTM INTERFACE CONTROLLER
CXD1969
Customer Requirements Specification
DESCRIPTION
&
Play’ and OpenCableTM
100 pin Plastic LQFP
The CXD1969 is an ‘Plug
CableCARDTM interface controller IC designed for use with
OpenCableTM compliant CableCARDTM modules. It performs
and the CableCARDTM. The IC communicates to the Host
either by a 68k-type or I2C connection. Communication
between the CXD1969 and the CableCARDTM is highly efficient
due to the inclusion of a fully integrated hardware Physical
layer.
MPEG2 Transport Stream interfaces are fully programmable
ensuring compatibility to commonly used Front End
demodulators and MPEG2 decoders.
A SCTE 28 compliant software stack is also available for this
device.

TS Input I/F is now serial only, (parallel TS input removed)
No change to TS Output I/F
Hot-swap state machine removed
Support for dual-slot removed
VCCSW and OVERLOAD functionality removed
VCCSEL changed to VPPSEL to support 3V3 or 5V PODs
Bidirectional OOB I/F added
Technology process change, some changes to DC spec
