Evaluation and Demonstration Boards and Kits provide engineers and scientists with a way to quickly evaluate the performance of their designs and showcase their work to customers and colleagues. The LMK04208EVM is a Evaluation and Demonstration Board and Kit targeted towards the telecommunications and consumer electronics markets. It uses Texas Instruments’s multi-GHz clock synthesizer to highly precisely maintain oscillator frequency accuracy over a wide temperature range.

The LMK04208EVM board is designed to allow users to input signals of various frequencies and to measure the accuracy of the outputs. It is based on the LMK04208 multiband clock synthesizer, which offers a high level of stability in system clock frequency. The board provides a variety of inputs and outputs to assist in the evaluation of the clock synthesizer including an oscillator input, reference clock input, and two outputs for each band of frequencies—a sine wave analog output and an HCSL (High-speed Current Steering Logic) digital output.

The LMK04208EVM works by rapidly switching the frequency of the outputs to match the input signal. The board uses a frequency synthesizer loop that has a low pass filter and a voltage-controlled oscillator (VCO). The VCO is driven by the error voltage generated by the delta-sigma modulator. The delta-sigma modulator converts the frequency difference between the input signal and the output signal to generate an error voltage that can be used to control the gain and the frequency of the VCO.

Black-box testing with LMK04208EVM allows engineers and scientists to quickly evaluate the performance of the LMK04208 multiband clock synthesizer in various in applications and environments. Adjusting the operating parameters and testing the board in different scenarios can further enhance the accuracy and performance of the board. This evaluation platform allows users to see the results of their design adjustments and determine the best design for a given application.

The LMK04208EVM is an Evaluation and Demonstration Board and Kit well-suited for both indoor and field deployment, making it an ideal solution for telecommunications and consumer electronics customers who need to evaluate clock synthesizers. With its high-precision frequency accuracy over wide temperature ranges, the LMK04208EVM provides engineers and scientists with a powerful tool to showcase their designs to customers and colleagues.
