1.536 GHz PLL with multi-protocol I/O
The Texas Instruments LMK04208NKDR is a PLLatinum™ clock jitter cleaner and frequency synthesizer that generates low-jitter clocks up to 1.536 GHz from a reference input. Its single PLL with integrated VCO targets high-speed data converter clocking, FPGA reference clocks, and RF LO generation where phase noise floor matters.
Signal format flexibility
Both inputs and outputs support LVCMOS, LVDS, and LVPECL levels, so the part interfaces directly with most ADC/DAC clock inputs, FPGA clock-capable pins, and RF synthesizer reference ports without external level translation. The 2:7 input-to-output ratio provides seven synthesised outputs from one of two selectable reference inputs.
Supply and thermal design-in
The operating temperature range is -45°C to 85°C.
