  David Park

  Part Number: LMX1204 Hi, How can measure actual delay time by Sysref delay? it's about few ps. Can high frequency oscilloscope measure this delay time? Thanks.

  Hi Sato-san, LMX1204 has channel to channel leakage around -45dBc, this also may affect on the PCB layout, which could couple the output on board too. Based on above setup, CLK1 may have leakage (-45dBc + switch pin isolation) along with switch pin-pin…

  Hi, I only need one 4GHz output for an ADC. If using the LMK as a distributor, I also need a splitter and divider considering the available LMX devices. The LMX1204 is not available. Below 100fs jitter would be a nice target figure. BR, Eirik
