GENERAL DESCRIPTION
The AL462 is a First-In-First-Out (FIFO) memory that consists of 512-Mbits of memory density and can be configured as a 16M x 32-bit FIFO at maximum R/W operating speed of 150 MHz for HD video applications up to 4K2K Ultra HD resolution. The AL462 Ultra HD (UHD) FIFO can be used in a wide range of applications such as multimedia, video capture systems and many other varieties of video data buffering applications. The size and high-speed data access allow HD video frame capture up to 4Kx2K resolutions.
