National Instruments CDA-2990 Clock Distribution Device

The NI CDA-2990 (Part Numbers: 784305-01, 784306-01, 140001B-03L) is a Clock Distribution Device from National Instruments. This device has 8 channels and AC input/output coupling. The CDA-2990 is widely used in the construction of multi-channel systems that operate in tight synchronization through a shared timing source. This 8-way distribution accessory operates with a fully integrated timing source. The NI CDA-2990 can synchronize as many as eight USRP devices in terms of both time and frequency. This Clock Distribution Device comes with PPS and 10 MHz inputs on the front panel. These inputs are then distributed to eight PPS SMA and eight 10 MHz outputs. The reference clock input power range is 0 dBm to 20 dBm for this device. To maintain signal integrity and level, each generated output signal is further amplified after getting divided.

The Clock Output on the National Instruments CDA-2990 Clock Distribution Device operates at 10 MHz frequency and provides up to 10 dBm power in regular conditions. The PPS output of the NI CDA-2990 can operate at 5 V maximum and can generate a logic-level pulse waveform. You can power this device through a 6 VDC to 15 VDC power supply with a maximum input power of 6 W. The NI CDA-2990 Clock Distribution Device accepts 10 MHz reference inputs and 1 pulse-per-second reference inputs from Rubidium standard or another compatible external source. These signals are amplified by active component for the generation of matched-length streams to eight output signals.
