HA SERIES HDTV FILTERS
LOW COST, MINIATURE FILTERS
This range of low cost filters offers near SMPTE 274M performance in a miniature space saving
package, suitable for single pass and HDTV monitor output applications.
• Near SMPTE 274M performance
• pin SIL package
• Ideal for analogue monitor outputs
• Aqueously washable versions available
• Pre and Post Luminance and Chrominance filters
• Integer N^o of clock delays between Luma and Chroma filters
