National Instruments 781419-02 Digitizer Adapter Module for FlexRIO

Part Number 781419-02 is the identifying part number for the National Instruments NI-5771 Digitizer Adapter Module for FlexRIO. The 781419-02 features two single-ended analog input channels that are simultaneously sampled. The connector type used for analog inputs is SMA and the input impedance is 50 Ω, per connector. The input channels are DC-coupled and the ADC can be identified as ADC08D1520. The digital data resolution is 8 bits for unsigned binary data while the absolute maximum voltage without damage is 6.3 Vpk-pk. Furthermore, the sample rate of the module is 1.5 GHz.

The internal sample clock on the 781419-02 uses a VCXO as the oscillator and has a frequency of 1.5 GHz. The CLK IN has a single-ended channel and uses a SMA connector with an input impedance of 50 Ω. The input line is DC-coupled and the input voltage range is 0.9 Vpk-pk to 3.5 Vpk-pk while the absolute maximum voltage without damage is 10 Vpk-pk. The duty cycle for CLK IN is 45% to 55%. The CLK OUT also shares similar characteristics as the CLK IN except that it is AC-coupled. 

The AUX I/O on the 781419-02 has 12 bidirectional channels (8 DIO and 4 PFI) and uses a HDMI connector. The interface standard is 3.3 V LVCMOS and the recommended operating voltage is -0.3 V to 3.6 V. Likewise, the maximum toggle frequency is 6.6 MHz while the overvoltage protection is ±10 V.

The 781419-02 measures (5.1 × 0.8 × 4.7 in.) in physical dimensions and weighs 413 g. There are 5 SMA, one SMB, and one HDMI connector in the front panel. The total power consumed by the module is 5.3 W. The module is recommended for operation between temperatures of  0 °C to 55 °C at a relative humidity of 10% to 90%. Likewise, it is designed for indoor use only and should be operated within a maximum altitude of 2000 m. On the other hand, it can be stored between -20 °C to 70 °C at a relative humidity of 5% to 95%.
