LOGIC Devices Incorporated LF3304

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. 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).

DESCRIPTION

In these modes the two memories can operate independently or with common control. 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.
