FEATURES

DESCRIPTION

The LF3304 is a dual line buffer/

FIFO, designed to operate at HDTV

rates. The LF3304 will operate in

two distinct modes: Line Buffer and

FIFO. In these modes the two memo-

ries can operate independently or

with common control.

The LF3304 comprises two 12-bit 4K

memories configurable in a variety of

ways including: Two 12-bit 4K deep

line buffers (independent lengths),

Three 8-bit 4K deep line buffers

LF3304 BLOCK DIAGRAM

(common lengths), One 12-bit 8K

deep line buffer, or Two 12-bit 4K

FIFOs (independent operation).

In FIFO mode, independent Read

and Write Resets give the designer

control over the internal pointers

providing flexibility not commonly

found in ordinary FIFOs.

The LF3304 operatates at a maximum

data rate of 100 MHz and is available

in a 100-lead PQFP package.
