Product Overview

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.
  • Integrated low noise 50MHz tunable crystal
  • Coarse frequency margining in percentage steps via I2C
  • Configurable output format of either LVPECL, LVDS or HCSL
  • Programmable output enable polarity
  • EEPROM allows for custom configuration for power up defaults
  • GUI platform for full access to LMK03328 registers and EEPROM
  • On-board USB to I2C programming interface
  • Powered over USB or externally (SMA connector)
  • LEDs indicators indicates device power and USB / I2C activity
  • Configurable output format of either LVPECL, LVDS or HCSL
