SP-20000M-PMCL / SP-20000C-PMCL- 18 -5.4 Pulse GeneratorThe SP-20000-PMCL series has a frequency divider using the sensor clock as the basic clock andfour pulse generators. In each Pulse Generator, various Clear settings are connected to GPIO.The following shows Pulse Generator default settings.Table - 9 Pulse Generator default settings5.4.1 Clock Pre-scalerClock pre-scaler (Divide Value) can set the dividing value of the frequency divider (12-bitlength) and the sensor clock is used for this. Four built-in pulse generators work by thesame clock. In the SP-20000-PMCL, the sensor pixel clock is 39.16 MHz.5.4.2 Pulse Generator SelectorThis is where you select one of the 4 pulse generators in order to set or modify itsparameters.Table - 10 Pulse Generator settingDisplay Name ValueClock Pre-scaler 1Pulse GeneratorSelectorPulse GeneratorLength StartPointEndPointRepeatCountClearSourceClearInverterClearActivationClearSyncMode- Pulse Generator 0 1 0 1 0 Off True Off Async Mode- Pulse Generator 1 1 0 1 0 Off True Off Async Mode- Pulse Generator 2 1 0 1 0 Off True Off Async Mode- Pulse Generator 3 1 0 1 0 Off True Off Async ModeNote:]When Pulse Generator Repeat Count is set to “0”, the camera is operating in free-running mode.However, based on the above default settings, Length=1, Start Point=0 and End Point=1, Pulse Generator stops at Highoutput. Therefore, if Start Point =0 and End Point=1 are configured, Length should be “2” as the minimum activewidth.Trigger Selectoritem DescriptionPulse Generator 0 If Pulse Generator 0 is selected, Length, Start Point, End Point, Repeat Count, Clear Source, ClearInverter, Clear Activation and Clear Sync Mode of Pulse Generator 0 are displayed under theselector.Pulse Generator 1If Pulse Generator 1 is selected, Length, Start Point, End Point, Repeat Count, Clear Source, ClearInverter, Clear Activation and Clear Sync Mode of Pulse Generator 1 are displayed under theselector.Pulse Generator 2 If Pulse Generator 2 is selected, Length, Start Point, End Point, Repeat Count, Clear Source, ClearInverter, Clear Activation and Clear Sync Mode of Pulse Generator 2 are displayed under theselector.Pulse Generator 3If Pulse Generator 3 is selected, Length, Start Point, End Point, Repeat Count, Clear Source, ClearInverter, Clear Activation and Clear Sync Mode of Pulse Generator 3 are displayed under theselector.
