LMX1404-EP Evaluation Module
Description
The LMX1404-EP evaluation module (EVM) is
designed to evaluate the performance of the
LMX1404-EP, which is a four-output, ultra-low
additive jitter radio-frequency (RF) buffer, divider and
multiplier. The device can buffer RF frequencies up
to 15GHz, multiply RF outputs up to 6.4GHz, and
divide outputs by up to 6.4GHz. This board consists of
an LMX1404-EP device and an integrated USB2ANY
programmer.
Features
• 300MHz to 15GHz output frequency
• 4 high-frequency clocks with corresponding
SYSREF outputs
– Shared divide by 2, 3, 4, 5, 6, 7 and 8
– Shared programmable multiplier ×2, ×3, and ×4
