LMX25311500EVAL Datasheet PDF - TI

The LMX2531 is a low power, high performance frequency synthesizer system which includes a fully integrated delta-sigma PLL and VCO with fully integrated tank circuit. The third and fourth poles are also integrated and also adjustable. Also included are integrated ultra-low noise and high precision LDOs for the PLL and VCO which give higher supply noise immunity and also more consistent performance.

●The LMX2531 Evaluation Board simplifies evaluation of the LMX2531 PLL/VCO synthesizer system. The board enables all performance measurements with no additional support circuitry. The evaluation board consists of a LMX2531 device, and a cable assembly.

●The cable assembly is bundled with the evaluation board for connecting to a PC through the parallel printer port. By means of MICROWIRE™ serial port emulation, the CodeLoader software included can be run on a PC to facilitate the LMX2531 internal register programming for the evaluation and measurement. In addition to this cable assembly, there is a microwire buffer board that ensures that the proper voltage levels are provided to the microwire inputs and also this reduces digital noise from computers through the parallel port.
