LF3320 - Horizontal Digital Image Filter

Description

The LF3320 filters digital images in the horizontal dimension at real-time video rates.

The input and coefficient data are both 12 bits and in two’s complement format.

The output is also in two’s complement format and may be rounded to 16 bits.

Features

LF3320 DEVICES INCORPORATED Horizontal Digital Image Filter LF3320 DEVICES INCORPORATED Horizontal Digital Image Filter DESCRIPTION The LF3320 filters digital images in the horizontal dimension at real-time video rates. The input and coefficient data are both 12 bits and in two’s complement format. The output is also in two’s complement format and may be rounded to 16 bits. The LF3320 is designed to take advantage of symmetric coefficient sets. When symmetric coefficient sets are used, the device can be configured as a single 32-tap FIR filter or as two separate 16-tap FIR filters. When asymmetric coefficient sets are used, the device can be configured as a single 16-tap FIR filter or as two separate 8-tap FIR filters. Multiple LF3320s can be cascaded to create larger filters.
