Other Parts Discussed in Thread: LMK04828, LMX2820
Hi Team,
We are using five LMK04828 in our design. For power supply, we are planning to use separate LDOs as per the Xilinx Clock 104 board (in clk104, 8 LDOs are used for individual power rails of LMK0428 for better noise rejection). But LMK04828 reference design from TI (ADC12DJ3200EVM) uses single LDO for all power supply of LMK04828. Is it possible to use single LDO and use ferrite beads for powering LMK04828 since we have board area constraints and want to reduce number of LDOs. What is the most critical power rails of LMK04828 is recommended to use external LDOs. Our requirement is to have very low noise supply for LMK04828.
Also we know that LMK04828 and LMX2820 has internal LDOs and we want to know the value of internal LDOs PSRR and output noise ripple.
