LMX2316TM Evaluation Board Operating Instructions General Description The LMX2316TM Evaluation Board simplifies the evaluation of the LMX2316TM 1.2 GHz PLLatinumTM frequency synthesizer. It enables all performance measurements, with no additional support circuitry. The board consists of a LMX2316TM device, a VCO module and a loop filter built by discrete components. The SMA flange mount connectors are provided for external reference input, RF output and the power & grounding connection. A cable assembly is bundled with the evaluation board for connecting to PC through the parallel printer port. By means of MICROWIRETM serial port emulation, the Codeloader software included can be run on PC to facilitate the LMX2316 internal register programming for the evaluation and measurement.
