LMX1204EVM User's Guide
The LMX1204EVM is designed to evaluate the performance of LMX1204. This board consists of an LMX1204
device and an integrated USB2ANY programmer.
The LMX1204 is an ultra-low additive-jitter RF buffer, divider, and multiplier, with integrated SYSREF generation
capability. The device can buffer RF frequencies up to 12.8 GHz, multiply RF outputs up to 6.4 GHz, and
divide outputs by up to 8 GHz. A separate auxiliary clock divider can be used for FPGAs or other logic ICs.
Each RF output (and the logic clock) is paired with a complementary SYSREF output with picosecond-precision
delay-tuning capability, and can be operated as a generator (with synchronization capability across multiple
devices) or as a repeater. The device runs from a single 2.5-V supply, and is programmed by a digital SPI
interface from a 1.8-V, 2.5-V, or 3.3-V bus controller.
