LF3311

LF3311 Horizontal / Vertical Digital Image Filter DEVICES INCORPORATED Improved Performance FEATURES 111 MHz Data Rate 12-bit Data and Coefficients On-board Memory for 256 Horizontal and 256 Vertical Coefficient Sets LF Interface™ Allows All 512 Coefficient Sets to be Updated Within Vertical Blanking Selectable 12-bit Data Output with User-Defined Rounding and Limiting Seven 3K x 12-bit, Programmable Two-Mode Line Buffers 16 Horizontal Filter Taps 8 Vertical Filter Taps Two Operating Modes: Dimensionally Separate and Orthogonal Supports Interleaved Data Streams Horizontal Filter Supports Decimation up to 16:1 for Increasing Number of Filter Taps 3.3 Volt Power Supply 5 Volt Tolerant I/O 144 Lead PQFP DESCRIPTION The LF3311 is an improved version of the LF3310 Horizontal/Vertical Digital Image Filter capable of operating at speeds of up to 111MHz. This improved speed will increase flexibility and performance. The added performance will enable you to use this device in more applications. For example, four interleaved data streams of 27MHz can now be processed within one device. The part is functionally identical to the LF3310 with the exception that the filter data path is specified to operate faster than the LF Control Interface. When operating the filter at speeds in excess of 90MHz, loading of coefficients via the LF Interface must be throttled to a maximum of 90MHz by asserting the PAUSE pin as required to allow sufficient setup time for the configuration data provided t...
