Texas Instruments LMX1204

Description

The LMX1204 evaluation module (EVM) is designed to evaluate the performance of the LMX1204, which is a four-output, ultra-low additive-jitter RF buffer, divider, and multiplier. This EVM can buffer RF clocking inputs up to 12.8 GHz, multiply x2, x3, or x4 in the output range of 3.2 GHz to 6.4 GHz, and divide inputs by up to 8. A separate auxiliary clock divider is included for FPGAs and logic clocking, and each output includes a SYSREF complement with picosecond precision and delay tuning capability. Multiple devices can be synchronized for wide clock distribution trees.

Features
