The FMC154 is an FPGA Mezzanine Module per VITA 57 specification that can be mounted on air and conduction-cooled carriers. The module provides a programmable Local Oscillator (LO) source via PLL and DDS using the Analog Devices AD9164 DDS. The flexibility and fast update rate make this module suitable for agile LO synthesis in frequency hopping and FM chirp radar systems.

The FMC154 can provide an LO output of up to 3 GHz via a wideband PLL, locked to either an external source or a reference from the FMC carrier. The PLL output is via a user-programmable low-pass filter.

The AD9164 provides direct digital synthesis using a 16-bit DAC running at 5 GSPS. The device supports automatic linear and nonlinear frequency sweeps, with phase tuning and frequency tuning to 20 pHz steps. The sampling clock can be synchronized to the input clock.
