The LMK61E2EVM is an ultra low jitter programmable oscillator evaluation module. This evaluation module provides a complete platform to evaluate the 90fs RMS jitter performance and configurability of the TI's LMK61E2 ultra low jitter programmable differential oscillator with integrated EEPROM and frequency margining capabilities. It is used as a high performance clock source for jitter critical applications and can easily be customized to any user desired frequency and output format. The onboard USB to I2C interface allows for device configuration via a software GUI and requires no external input or power for device operation. The edge-launch SMA ports provide access to the LMK61E2's differential clock output for interfacing to test equipment or reference boards using commercially available coaxial cables, adapters or baluns. This connectivity enables integrated system level testing between TI's LMK61E2 and third-party FPGA/ASIC/SoC reference boards.
