Multiformat Video Crosspoint with
Integrated Sync Separator
The ISL59450 is a video crosspoint switch supporting
multiple video input formats (CVBS, S-Video, YPbPr, and
RGB signals). Embedded anti-aliasing filters with
programmable corner frequencies eliminate glitch noise from
video DACs. The large number of inputs, wide range of
formats, integrated anti-aliasing filters, and dual
sync-separators make the ISL59450 an ideal choice for
video switching in nearly all display systems.
The ISL59450 is available in a 128 Ld MQFP package and is
specified for operation over the full -40°C to +85°C
temperature range.
