National Instruments 781659-02 Digitizer Adapter Module for FlexRIO
Part Number 781659-02 is the identifying part number for the National Instruments NI-5733 Digitizer Adapter Module for FlexRIO. The 781659-02 features two analog input channels that are single-ended and can be simultaneously sampled. The channels support a BNC connector and the input impedance is 50 ohms per connector. It supports both AC and DC coupling (software selectable). Likewise, the gain can be set to 0 dB, 6 dB, or 12 dB whereas signal paths can be selected as Filter bypass, 7th-order Elliptic filter, or 7th-order Bessel filter with software.
The 781659-02 has a digital data resolution of 16 bits and an absolute maximum voltage of ±10 V DC, 10 Vpk-pk AC. The ADC DC offset is ±7.1 mV while the AC-coupling low cut-off frequency (-3 dB) and DC-coupling low cut-off frequencies are 20 kHz and 0 Hz respectively. The internal sample clock on the 781659-02 is based on a VCXO oscillator having a frequency of 120 MHz ± 100 ppm. Furthermore, the CLK IN has a single channel and uses an SMB connector. The input impedance is 50 ohms and it supports AC coupling only. Similarly, the input voltage range is 0.40 Vpk-pk to 5.2 Vpk-pk while the absolute maximum voltage is ±8.0 V DC, 8.0 Vpk-pk AC. Moreover, the duty cycle ranges from 40% to 60%.
The Aux I/O on the 781659-02 has 12 bidirectional channels (8 DIO and 4 PFI) and uses a HDMI connector. The interface uses a 3.3 LVCMOS interface and the recommended operating voltage is –0.3 V to 3.6 V. Likewise, the overvoltage protection in these channels is ±10 V while the +5 V voltage tolerance is 4.2 V to 5 V. The maximum power at +5 V is 10 mA and the maximum toggle frequency is 6.6 MHz. The total power consumed by the 781659-02 in typical operation is 2.6 W. The module measures (5.1 x 0.8 x 4.7 in.) in physical dimensions and weighs 313 g. The module operates between 0 °C to 55 °C at a relative humidity of 10% to 90% and within a maximum altitude of 2000 m.
