b:  CHIP SUMMARY 
 

M30620

: 16-BIT CMOS SINGLE-CHIP MICROCOMPUTER 

The single-chip microcomputer operate using sophisticated instructions 
featuring a high level of instruction efficiency. With 1M bytes of address space, 
they are capable of executing instructions at high speed. In addition, this 
microcomputer contains a multiplier and DMAC which combined with fast 
instruction processing capability. 
 
   

SVP-EX52

: VIDEO DE-INSCALE 

The SVP_EX-52 video processor is a highly integrated system on a chip 
device, targeting the converging HDTV-ready and PC-ready and LCD TV, PDP 
TV, and DLP TV applications where high precision processing of video and 
data are the requirements. SVP_EX-52 contains dual-purposed triple 10-bit 
high-precision and high-speed video ADCs for both PC and video inputs, a 
high performance 5th generation multi-format 3D digital comb video decoder 
that supports NTSC, PAL and SECAM, an HDTV sync separator, motion 
adaptive de-interlacing engine, and the video format conversion engine,   

 

   

MST3788

: 8-bit Analog and HDCP Interface for Advanced Digital Displays 

The MST3788 integrates both analog interfaces and HDCP compliant 
receivers for enabling advanced digital display devices such as digital TVs, 
plasma displays, LCD TVs and projectors to receive and display. Compliant 
with the HDCP 1.0 specification, the MST3788 enables consumer electronic 
devices to receive uncompressed, high quality, digital video HD content over a 
single, low-cost DVI cable. 
 
   

MSP3450G

: AUDIO DECODER   

The MSP 34x0G family of single-chip Multistandard Sound Processors covers 
the sound processing of all analog TV-Standards worldwide,
