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.
