Product Details

TThe EV-ADF4378SD1Z evaluates the performance of the ADF4378 frequency synthesizer with an integrated voltage controlled oscillator (VCO) for phase-locked loops (PLLs). A photograph of the EV-ADF4378SD1Z is shown in Figure 1. The EV-ADF4378SD1Z contains the ADF4378 frequency synthesizer with an integrated VCO, a USB interface, power supply connectors, on-board reference oscillator, propagation delay calibration paths, and Subminiature Version A (SMA) connectors. The outputs are AC-coupled with 50 Ω transmission lines, which make the outputs suitable to drive 50 Ω impedance instruments. The EV-ADF4378SD1Z requires an SDP-S board (not supplied with the kit). The SDP-S allows software programming of the EV-ADF4378SD1Z with ACE software.

Full specifications on the ADF4378 frequency synthesizer are available in the ADF4378 data sheet available from Analog Devices, Inc., and must be consulted with this user guide when using the EV-ADF4378SD1Z evaluation board.
