National Instruments 784306-01 Clock Distribution Device
National Instruments part number 784306-01 is an identifying part number for the CDA-2990, a Clock Distribution Device with a Reference Clock Input and Output Frequency of 10 MHz. The NI 784306-01 is an 8-channel device with AC input/output coupling, widely used for building multi-channel systems that require tight synchronization via a shared timing source. It features a fully integrated timing source and can synchronize up to eight USRP devices for both time and frequency. The front panel includes PPS and 10 MHz inputs, which are distributed to eight PPS SMA and eight 10 MHz outputs.
The reference clock input power range is 0 dBm to 20 dBm. Each output signal is amplified after division to maintain signal integrity and level. The Clock Output of the 784306-01 Clock Distribution Device operates at a 10 MHz frequency and typically provides up to 10 dBm of power. The PPS output can operate at a maximum of 5 V, generating a logic-level pulse waveform. This device is powered by a 6 VDC to 15 VDC power supply, with a maximum input power of 6 W.
The NI 784306-01 accepts 10 MHz reference inputs and 1 pulse-per-second (PPS) inputs from a Rubidium standard or other compatible external sources. These signals are amplified by active components to produce matched-length streams to the eight output signals. The GPS Disciplined Oscillator (GPSDO) of this device operates with a voltage of 5 V and consumes 0.7 W of power. It receives GPS signals at the L1, C/A frequency of 1,574 MHz. The 784306-01 is compatible with both active and passive GPS antennas, ensuring flexibility and reliability in various applications. This setup allows the GPSDO to provide precise timing and synchronization by leveraging GPS signals, making it suitable for applications that require accurate timekeeping and frequency stability.
