ADV601LC
APPLYING THE ADV601LC
This section includes the following topics:
• Using the ADV601LC in computer applications
• Using the ADV601LC in standalone applications
• Configuring the host interface for 6- or 32-bit data paths
• Connecting the video interface to popular video encoders and
decoders
• Getting the most out of the ADV601LC
The following Analog Devices products should be considered in
ADV601LC designs:
• ADV7175/ADV7176—Digital YUV to analog composite
video encoder
• AD722—Analog RGB to analog composite video encoder
• AD1843—Audio codec with embedded video synchronization
• ADSP-21xx—Family of fixed-point digital signal processors
• AD8xxx—Family of video operational amplifiers
Using the ADV601LC in Computer Applications
Many key features of the ADV601LC were driven by the demand-
ing cost and performance requirements of computer applications.
The following ADV601LC features provide key advantages in
computer applications:
• Host Interface
The 512 double word FIFO provides necessary buffering of
compressed digital video to deal with PCI bus latency.
• Low Cost External DRAM
Unlike many other real-time compression solutions, the
ADV601LC does not require expensive external SRAM
transform buffers or VRAM frame stores.
