TMC2246AX1 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.

Video Filters

ML6426X5 Features
5V ±10% operation
RGB/YUV filters for ATSC Digital Television VESA Standard
2:1 Mux Inputs for multiple RGB/YUV inputs
Triple Reconstruction Filter options for 6.7, 12, 24, 30, and 36MHz to handle various line rates
Multiple ML6426 outputs can be paralleled to drive RGB/YUV outputs at different frequencies for various line rates by means of Disable/Enable pin.
6dB drivers and sync tip clamps for DC restore
DC restore with minimal tilt
0.4% differential gain on all channels 0.4° differential phase on all channels 0.8% total harmonic distortion on all channels
2kV ESD protection

ML6426X5 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.
