Picosecond Pulse Labs manufactures risetime filters that are ideal for HDMI testing. Risetime filters are sometimes also called Transition Time Converters or TTC's.
Popular HDMI risetimes (10% - 90%) are 60ps, 150ps, 200ps, 220ps, 450ps, and 1200ps.
In addition to these standard risetimes, PSPL can custom build filters with any user specified risetime from 35ps to 10ns.
PSPL ristime filters are specified with 10% - 90% risetimes. Use the following formula to convert between 10% - 90% risetime and 20% - 80% risetime.
Tr (10% - 90%)* 0.66 = Tr (20% - 80%)
