Figure 2: FMC-Pico-1M4 side 2 Figure 1: FMC-Pico-1M4 side 1 Figure 3: FMC-Pico-1M4 front view The FMC-Pico-1M4 device is composed of the following building blocks: ... - Page 10 (+5 V, -5 V and 2.5 V), which are required for the high- quality analog-to-digital signal conversion. There are several light emitting diodes (LEDs) on the FMC-Pico-1M4 board. The four green ones are signaling the presence of the power supply voltages that are supplied from the carrier board (12P0V, 3P3V, 3P3VAUX and VADJ).

Page 17: Controlling The Fmc
FMC-Pico-1M4 User’s Manual 3. Controlling the FMC 3.1 Digital Interface The ADCs simultaneous conversion is controlled by CNV signal. A rising edge on CNV will starts the conversion of the 4 input channels. Once a conversion has been initiated, it cannot be restarted until the conversion is completed. For optimum performance, CNV should be driven by a clean low jitter signal. -
