Description
The CXD1807Q has functions to decode CD-G
commands written in the CD subcode and write
them into the DRAM to display them. It also has a
built-in RGB 4-bit D/A converter. By adding 256K
bits of DRAM and a video encoder, a CD graphics
system can be configured.
Functions
Real-time correction of subcode errors
