Faraday FL471 Practical 601 filter Datasheet

PRACTICAL 601 FILTERS
YUV ANTIALISING
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
