CX92755 User Interface and Media Processor
Complete Multimedia Solution on a Single Chip
Conexant’s CX92755 System-on-Chip (SoC) is
an integrated display, media, video, and image
processor delivering a new level of performance
and system integration. The SoC builds on
Conexant’s strengths in image and mixed-signal
processing, and integrates high performance
video codec and graphics processing hardware.
To support robust system design and lower Bill
of Material (BOM) costs, the CX92755 also
integrates a stereo Class-D amplifier, microphone
input, touchscreen controller, and power supply
controller.
encode and decode, the CX92755 supports a
BT.656 compatible video-in port for video capture
applications. For advanced GUI operations,
the CX92755 supports a hardware graphics
processing unit (GPU). This GPU includes a
Display List Processor along with Alpha Blend and
Clipping Units to support complex, independent
UI operations. The CX92755 features a flexible,
programmable LCD interface, hardware JPEG
