Component Analog TV Sync Separator
General Description
The MAX9568 video sync separator extracts sync timing
information from standard-definition (SDTV), extended-
definition (EDTV), and high-definition (HDTV) component
video signals. This device is designed for reliable opera-
tion in the presence of copy protection schemes such as
MACROVISION^®.
The MAX9568 is a stand-alone device and requires no
external components for timing or biasing. High-imped-
ance video inputs prevent loading of the input signal
and eliminate the need for buffering.
The MAX9568 is available in a 16-pin QSOP package.
The device is specified over the -40°C to +85°C tem-
perature range.
