LF3338 DEVICES INCORPORATED 8-Bit Vertical Digital Image Filter LF3338 DEVICES INCORPORATED 8-Bit Vertical Digital Image Filter DESCRIPTION The LF3338 is a lower cost version of the 12-bit LF3330 and is suited for multimedia and special effects systems, projectors, plasma display panels, scan converters, set-top boxes, and other consumer applications. This device filters digital images in the vertical dimension at real-time video rates. Input data is 8 bits and coefficient data is 12 bits and both are in two’s complement format. The output is also in two’s complement format and may be rounded to 16 bits. The filter is an 8-tap FIR filter with all required line buffers contained onchip. The line buffers can store video lines with lengths from 4 to 3076 pixels.
