GENERAL DESCRIPTION  
The ADA4424-6 is a high performance video reconstruction filter  
specifically designed for consumer applications. It consists of a  
standard definition (SD) section with two fifth-order Butterworth  
filters and a high definition (HD) section with three fifth-order  
filters. The SD section contains an internal Y/C summer for CVBS  
output, whereas the HD section provides selectable corner  
frequencies for either extended definition (ED) or HD signals.  
The luma channels (Y_IN, HY_IN) of the ADA4424-6 are  
capable of detecting and cancelling dc input offsets of up to  
1.1 V. Four distinct modes of detection/cancellation are  
available.  
The output drivers on the ADA4424-6 feature rail-to-rail outputs  
with 6.2 dB gain. An on-board charge pump allows the outputs to  
swing up to 1.4 V below ground, eliminating the need for large  
coupling capacitors. Each output is capable of driving two 75 Ω  
doubly terminated cables.  
The ADA4424-6 filter/buffer section operates from a single 3.3 V  
supply. Full support for D-terminal (EIAJ RC-5237 D5) and S1/S2  
signaling is provided, along with a dedicated 5 V supply pin.  
Separate enable pins are provided for the SD and HD sections.  
The ADA4424-6 is available in a 38-lead TSSOP and operates in  
the industrial temperature range of −40°C to +85°C.
