AL462 4K2K Ultra HD FIFO Datasheet
1 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.
The AverLogic AL462 UHD FIFO memory provides completely independent input and
output ports. The built-in address and pointer control circuits provide a straightforward bus
interface to sequentially read/write memory that can reduce inter-chip design efforts.
The AL462 uses high performance process technologies support extended controller
functions, like control signals polarity selectable, output clock phase adjustment, two frame
mode (double buffer), that allow easy operations on FIFO read/write for uses in
broadcasting systems, security systems, cameras and many other applications.
The AL462 is designed and manufactured using state-of-the-art technologies with low
power consumption AC characteristics (1.8/3.3V power supply) facilitating high
performance and high quality applications.
The chip is available in LFBGA 249-ball package; the small footprint allows product
designers to keep board real estate to a minimum.
