VP520 Features
Lower Power, pin compatible replacement for VP520
Converts CCIR601 luminance and chrominance to CIF or QCIF resolution, and vice versa, using a 27MHz system clock
Luminance and chrominance channels have their own sets of horizontal and vertical filters with on chip line stores
Each filter set may be configured to either decimate or interpolate
NTSC line insertion or removal mode
Produces/expects CIF/QCIF data in macroblock format
120 Pin QFP Package

VP520 Description
The VP520S is designed to convert 16 bit multiplexed luminance and chrominance data between CCIR601 and CIF/QCIF resolutions. Vertical and horizontal FIR filters are provided, with the vertical filters supported by on chip line stores. The coefficients used by the filters are user definable, and are down loaded from an independent host data bus. An internal address generator supports an external DRAM frame store, and also provides line to macroblock conversion.
