MODEL V730 OPTICAL/ELECTRICAL CONVERTER VME MODULE

Six channels of logic-level optical-to-electrical conversion Propagation delay below 5 nanoseconds Jitter below 5 picoseconds RMS Accepts 850 nm optical input Outputs TTL and NIM logic levels For use in a VME rack, or standalone with available external power supply

The V730 is a six-channel logic-level optical-to-electrical converter, packaged as a single-width, 6U VME module. When used with compatible Highland optical transmitter modules, the V730 provides fast, low-jitter, EMI-proof distribution of pulses, triggers, and precision timing signals. The V730 accepts 850 nm optical input through multimode ST connectors using either single- or multi-mode fiber. Nominal input power is 1 mW with a detection threshold of 250 uW. The module?s electrical outputs produce TTL and NIM logic levels, with selectable polarity. The user can independently configure each channel?s logic level and polarity. Output drive is 0 to 5 volts into a 50-ohm load.

Safety features include a logic-level GATE input to enable/disable the output drivers and a front-panel SAFETY toggle switch that removes power from the output drivers. The module receives power from the VME backplane; it does not connect to the VME data bus, and passes all grant signals. The V730 also accepts power from the optional Model J190 power supply for standalone use.
