In many 4:2:2 YUV format A-D and D-A video interface applications operating at standard

sampling rates of 13.5 MHz for the luminance (Y) channel and 6.75 MHz for the Colour Difference

(U and V) channels a filter meeting the full requirements of Rec. ITU-R BT. 601-5 should be

specified but cost may be prohibitive. Practical 601 filters allow a small compromise in

performance resulting in significant cost savings which may be acceptable.

• Choice of package format to suit requirement

• Flat and Sinx/x versions

• Tight passband ripple specification

• Aqueously washable versions available
