WILLSEMI WS71441S-8/TR

The WS71441 is a low power, HD composite video filter and comparator on a single chip. Drawing less than 15mA supply current over the full operating temperature range. WS71441 integrate high-performance low-cost 54MHz composite video reconstruction filter, it incorporates one high-definition (HD) filter channel. The HD filters can be bypassed to support HDCVI 1080i/720p video. The WS71441’s on-board comparator is high-speed (28ns propagation delay under 2.7~5.5V wide supply range) and low power consumption. The WS71441 is available in SOP-8L package and MSOP-8L package. Its operation temperature range is from -40°C to +85°C.
