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

(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.
