The LMX1205 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 EVM 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 includes a system reference (SYSREF) complement with picosecond precision and delay tuning capability. Multiple devices can be synchronized for wide clock distribution trees.
