LMX2582: LMK04828,LMX2582,HMC987(ADI buffer)- LDO recommendation and single LDO for LMX2582 and HMC987

Hi TI,

We are going to use LMK04828, LMX2582 and HMC987 for clocking ADC12DJ3200. There will be three ADCs on single PCB.

LMK04828 will be used to provide SYSREF to ADC and FPGA.

LMX2582 will generate sampling clock and HMC987 will buffer this clock and provide sampling clock from three of its outputs to three ADC12DJ3200.

We will be using LDOs to power LMK,LMX and HMC987.

We are planning to use single separate LDO for LMK04828 and a single separate LDO for both LMX2582 and HMC987.

Please verify this:

 Can we use signle LDO for both LMX2582 and HMC987 or we need to use separate LDO for LMX2582 and HMC987 for better performance?

Also please suggest some LDOs which we can used with LMK and LMX,HMC987, without compromising LMK,LMX and HMC performance.

Thanks,

Lalit
