The AL422 from AverLogic is a video frame memory used to buffer audio/video/graphic data for digital processing, timing correction or format conversion. It is manufactured with state-of-the-art embedded DRAM technology for applications in TVs, VCRs, scan converters and digital video systems.
The device consists of 3 Mb of DRAM, and is configured as 39 3216 words x 8 bit FIFO (first in first out). The high-speed and low-power consumption are achieved by using 0,35 µm technology with embedded EDO dynamic memory. The interface is user-friendly since all complicated DRAM operations are already managed by the internal DRAM controller. Current market sources of similar memory (field memory) provide limited memory size which is only enough for holding a TV field, but not enough for a whole PC video frame, which normally contains 640x480 or 720x480 bytes. The AL422 provides 50% more memory to support high resolution for digital PC graphic or video applications
The AL422 can accept either 3,3 or 5 V power with slightly different external configuration. It supports VGA and CCIR resolutions. Read/write cycle time is 20 ns, and access time 15 ns and comes in standard 28-pin SOP package.
