Texas Instruments LMX1205EVM Evaluation Module (EVM)

Texas Instruments LMX1205EVM Evaluation Module (EVM) is designed to evaluate the performance of the LMX1205, which is a four-output, ultra-low additive jitter radio-frequency (RF) buffer, divider and multiplier. This evaluation module can buffer RF clocking input up to 12.8GHz, multiply input by up to eight in the output range of 6.4GHz to 12.8GHz, and divide inputs by up to eight. A separate auxiliary clock divider is included for field-programmable gate arrays (FPGAs) and logic clocking, and each output consists of a system reference (SYSREF) complement with picosecond precision and delay tuning capability. Multiple Texas Instruments LMX1205 devices can be synchronized for wide clock distribution trees.
