Texas Instruments LMK05318BEVM Clock Evaluation Module (EVM)

Texas Instruments LMK05318BEVM Clock Evaluation Module (EVM) is designed for the evaluation of the LMK05318B, a network synchronizer clock device. The evaluation module can be used as a flexible, synchronous clock source for rapid evaluation, compliance testing, and system prototyping. SMA ports provide access to the LMK05318B clock inputs and outputs for interfacing to 50Ω test equipment. Onboard XO options are included but can be reworked using the various XO/TCXO/OCXO footprint options or else bypassed to use the external SMA input. The Texas Instruments LMK05318BEVM provides a USB-based interface to access the I2C/SPI bus and control pins of the LMK05318B. The TICS PRO software GUI can be used to program the LMK05318B’s registers and EEPROM to store custom start-up clock settings.

Features

  • One Digital PLL (DPLL) with programmable bandwidths and two fractional analog PLLs (APLLs) for flexible clock generation
  • Two reference inputs to the DPLL supporting hitless switching & holdover
  • Eight output clocks with 50fs RMS phase jitter (12kHz to 20MHz)
  • On-chip EEPROM for custom start-up clock configurations
  • Flexible oscillator sources: onboard XOs or external SMA input options
