Anti-Aliasing and Reconstruction
TFT range
YUV COMPONENT SAMPLING
These very small, low cost filters are intended for use with A-D and D-A video converters where
some deviation from full ITU-R BT601 standard can be tolerated, ie single pass applications.
These filters are designed for use in 4:2:2 sampling systems, ie 13.5 MHz for the luminance (Y)
channel and 6.75 MHz for the chrominance (U and V) channels.
• Ideal for single pass or monitor outputs
• Choice of package format to suit requirement
• Small size
• Excellent pulse characteristics
