National Instruments 784429-01 Digitizer Adapter Module for FlexRIO

Part Number 784429-01 is the identifying part number for the National Instruments NI-5753 Digitizer Adapter Module for FlexRIO. The 784429-01 features 16 analog input channels that are AC-coupled. Note that the module also comes in a DC-coupled variant (part number 784429-02) featuring 12 input channels. The input impedance is 50 Ω and the maximum sample rate is 120 MS/s. The frequency range for this AC-coupled variant is 0.1 MHz to 250 MHz and the ADC is identified with part number AD9653. 

The internal sample clock on the 784429-01 has a frequency range of 120 MHz. On the other hand, the internal reference has a frequency of 10 MHz.Furthermore, the external sample clock (CLK IN) also has a frequency of 120 MHz while the external reference has 10 MHz. Likewise, the input impedance in CLK IN is 50 kΩ and the input is AC-coupled. 

The 784429-01 has 12 bidirectional AUX I/O channels (8 digital I/O and 4 PFI). The digital inputs support a minimum high-level voltage (VIH) of 2.0 V and a maximum low-level voltage (VIL) of 0.8 V. On the other hand, the digital outputs have a maximum low-level output voltage (VOL) of 0.4 V, and the minimum and maximum high-level output voltage (VOH) are 2.7 V and 3.6 V respectively. The maximum toggle frequency for all outputs is 100 MHz while the overvoltage protection is ±10 V.

The 784429-01 measures (4.6 x 0.8 x 4.0 in.) in physical dimensions and weighs 317.5 g. It features one ganged MCX connector, one SMB connector, and one HDMI connector. The total power consumed by the module is 5.4 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 -40 °C to 71 °C at a relative humidity of 5% to 95%.
