National Instruments 781267-01 Transceiver Adapter Module for FlexRIO

Part Number 781267-01 is the identifying part number for the National Instruments NI-5781 Transceiver Adapter Module for FlexRIO. The 781267-01 features two differential analog input channels that are simultaneously sampled. The connector type used for analog inputs is MCX and the input impedance is 50 Ω, per connector. Under normal operating conditions, the input range is fixed at 2 Vpk-pk for differential mode and 1 Vpk-pk for single-ended mode. The input channels are DC-coupled and the ADC has a resolution of 14 bits and can be identified as AD9640/105. The module has a digital data range of ±8,191. Furthermore, the sample rate of the internal sample clock is 10 MHz to 100 MHz while the sample rate of the external clock is 20 MHz to 100 MHz. 

On the other hand, the 781267-01 also features two differential analog output channels and uses the MCX connector. The maximum input in these channels is ±4 V per connector while the digital data range is ±32,767. Note that the maximum sample rate is 400 MS/s. Furthermore, it uses a 16-bit DAC that is identified with a part number AD9777. The internal sample clock on the 781267-01 uses a VCXO as the oscillator and has a frequency of 100 MHz ± 25 ppm. The CLK IN has a single-ended channel and uses an MCX connector with an input impedance of 50 Ω. The frequency range is 20 MHz to 100 MHz and the input line is AC-coupled. 

The 781267-01 measures (5.1 × 0.8 × 4.7 in.) in physical dimensions and weighs 284 g. There are 10 MCX and one 9-pin DIN( with shield) connectors in the front panel. The total power consumed by the module is 5.5 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%.
