The IO buffer technology determines voltage levels of a signal on the interface, as well as the timing with respect to the synchronizing signal
; for example, data (or address or command or control) signal valid time with respect to clock or strobe from a driving IO buffer, and setup and hold times of data signals with respect to clock or strobe required by the receiving IO buffer.
This frequency conversion feature had been required in the past when data centers used the 60 Hz sine wave as a synchronizing signal
. However, today's data center and the Internet are equipped with power supplies that tolerate a wide range of frequency to enable application worldwide.
The fully-featured SPG8000 comes standard with individually timeable black burst (with VITC support) and HDTV tri-level sync outputs, linear time code (LTC) outputs and network time protocol (NTP) server support - all of the timing and synchronizing signals
required in a video broadcast or production facility.
The need for the instrumentation to generate and receive synchronizing signals
also is a requirement.
were sent from an overhead CCD camera (Hitachi KP-M2U) to a 400 MHz Pentium computer running MetaMorph[TM] imaging software; the computer then synchronized the firing of the laser with the acquisition of images.
