AL422B-PBF Product Details
The AL422B-PBF 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 AL422B-PBF consists of 3Mbits of DRAM, and is configured as 393,216 words x 8 bit FIFO (first in first out). The high speed and low power consumption are achieved by using 0.35 micron process technology with embedded EDO dynamic memory. The interface is very user-friendly since all complicated DRAM operations are already managed by the internal DRAM controller. Current sources of similar memory (field memory) in the market 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 AverLogic AL422B-PBF provides 50% more memory to support high resolution for digital PC graphic or video applications. The 50% increase in speed also expands the range of applications. The AL422B-PBF can accept either 3.3V or 5V power with slightly different external configuration. The internal voltage regulator can convert 5V power to 3.3V for the embedded DRAM and logic circuitry when 5V power is applied to VDD pin (#10) only and leave the DEC pin (#19) decoupled by a capacitor of 2.2uF to ground. The regulator can also be bypassed when 3.3V power is applied to both VDD and DEC pins. In either case the AL422B-PBF is 5V or 3.3V I/O tolerant. The 3.3V configuration consumes less power and is free from noise interference from the voltage regulator so may be more ideal for high-speed applications. Please note that using the AL422B with 5V configuration can directly replace the previous AL422V5; using it with 3.3V configuration can directly replace the previous AL422V3. No additional modification is required.
