Single LDO for powering LMX2582(RF synthesizer) and HMC987(Clock Buffer)

by Alan   Last Updated July 12, 2019 11:25 AM - source

I am using LMX2582 and HMC987 for providing sampling clocks to three RF sampling TI ADC12DJ3200.

LMX2582 will generate 3.2GHz and give it to HMC987. Then three outputs of HMC987 will be connected to clock inputs of three ADC12DJ3200.

Both LMX2582 and HMC987 will be running at 3.2GHz.

Can I use single LDO to power both LMX2582 and HMC987 or I need to use separate LDOs for LMX2582 and HMC987 for best performance?
