BKPF-L704

The BKPF-L704 is an analog I/O black burst regenerator
board with a range of NTSC system applications. For
example, it can be used in a mixed analog/digital system,
delaying the sync signal to the analog equipment to
compensate for the longer video delay of the digital
equipment. The BKPF-L704 is an ideal and cost-effective
tool for use in systems that are making the transition from
analog to digital—where both analog and digital
equipment has to co-exist. For this type of application,
the BKPF-L704 exactly meets customer needs.
