GeckoFlex 8937 SDI/ASI Reclocking Equalizing Distribution Amplifier

This distribution amplifier is ideal for medium- to long-distance distribution of digital signals. It is fully DVB ASI compatible so it can be used in any application where standard SDI video or ASI signals are to be copied and distributed. The standard reclocker circuit greatly reduces jitter induced over long cable runs or from unstable sources of standard data rate signals. The reclocker can easily be disabled to pass SMPTE 310M and other non-standard data rate signals. A user-enabled video presence detection feature generates SNMP traps that can be sent to our NetCentral™ SNMP manager or other SNMP systems.
