TMC2246AX2 Description
The TMC2246A is a video-speed convolutional array composed of four 11 x 10 bit registered multipliers followed by a summer and an accumulator. All eight multiplier inputs are accessible to the user and may be updated every clock cycle with integer or fractional two”s complement data. A pipelined architecture, fully registered input and output ports, and asynchronous three-state output enable control simplify the design of complex systems.

ML6426X1 Description
The ML6426 are a family of triple video filters with buffered outputs. There are several versions of the ML6426, each with different passband cut-off frequencies of 6.7MHz, 12MHz, 24MHz, 30MHz and 36MHz. Each channel contains a 4 th order Butterworth lowpass reconstruction video filter. The filter is optimized for minimum overshoot and flat group delay and guaranteed differential gain and phase at the outputs of the integrated cable drivers.

VP520 Description
PAL/NTSC to CIF/QCIF Converter
VP520 Vendor
Zarlink Semiconductor
VP520 Categories
Video Converters

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.
