Flexible Configuration Options for Any System ArchitectureThe SPG9000 offers a complete set of reference inputs and outputs, supporting a wide variety of system designs. The base configuration includes all the features of a complete sync pulse generator, and all options are licensed so that they can be purchased with the base unit or any time later to upgrade the system. The SPG9000 has multiple options for setting the internal clock reference (frequency and time-of-day). It can lock to a received GNSS signal, to another PTP grandmaster, or to another sync generator or an external atomic clock using the analog genlock input. The loop-through genlock input can lock to many different types of analog synchronization signals, including NTSC and PAL black burst, HD tri-level sync signals for all common 1080-line and 720-line frame rates and formats, and continuous wave (CW) signals at 10 MHz.
