GENERAL DESCRIPTION
GENERAL DESCRIPTION
The ADA4420-6 is a low cost video reconstruction filter specifically
The ADA4420-6 is a low cost video reconstruction filter specifically
designed for consumer applications. It consists of six independent
designed for consumer applications. It consists of six independent
sixth-order Butterworth filters/buffers, three for standard
sixth-order Butterworth filters/buffers, three for standard
definition (Y/C or CVBS) and three for high definition
definition (Y/C or CVBS) and three for high definition
component signals (YPbPr or RGB).

Each channel features a transparent sync tip clamp, allowing ac
coupling of the inputs without requiring dc restoration.
The output drivers on the ADA4420-6 have rail-to-rail output
capabilities with 6 dB gain. A built-in offset of 250 mV allows
the outputs to be dc-coupled, eliminating the need for large
coupling capacitors. Each output is capable of driving two 75 Ω
doubly terminated cables.
The ADA4420-6 is available in a 16-lead QSOP and operates in
the extended industrial temperature range of −40°C to +85°C.

... Inputs to the ADA4420-6 can be ac- or dc-coupled. For dc-coupled inputs, the signal must be completely contained within the input range 2.1 V. When using ac-coupled inputs, the lowest point of the signal is clamped to approximately 0 V. The ADA4420-6 outputs can be either ac- or dc-coupled. When driving single ac-coupled loads in standard 75 Ω video distribution systems, a minimum capacitance of 220 μ ...
