  AL460A - Full HD Video FIFO

 
Description

The AL460 consists of 128Mbit of memory density, and is configured as 8,192K x 16 bits FIFO (First-In-First-Out), the optimized access scheme offers maximum R/W operating speed up to 150 MHz. The FIFO provides simple and easy-to-use user interfaces facilitating usage in a wide range of applications, such as Multimedia systems, video capture systems, and various video data buffering applications.

The extensive memory size and high data-access-speed allow video frame capturing up to Full HD (1080p) resolution. Complementing the Double Buffer mode, 2 banks serve as upper and lower banks (with 4,096k x 16-bit of each bank), AL460 can be further manipulated into more sophisticated applications. The R/W operations of corresponding banks are acknowledged while high/low signals present at the bank control pins.

All AL460 FIFO specifics, like completely independent input and output controls, built-in address and pointer control circuits, bank switching and other management tasks provide data integrity during access and straightforward bus interface for a sequential data read/write that reduce inter-chip design efforts.

The Double-Buffer mode allocates video data capture without reading a mixed old and new data frames. The polarity control seamlessly matches the controller waveform without additional glue-logic.

The AL460 is also implemented with high performance process technologies with extended controller functions (write mask, read skip .. etc.); allowing easy operation of FIFO read/write for use in broadcasting systems, security systems, cameras, and many other applications.

Designed and manufactured using state-of-the-art technologies, AL460 achieved high performance and low power consumption AC characteristics (2.5/3.3V power supply), for the most sophisticated applications.

The chip is available as an LQFP-128 package; the small footprint keeps real estate of any designs to a minimum.
