AD9528 has a VCXO input described as PLL1 oscillator input.
I want to use AD9528 for two reasons:
1-) SYSREF JESD204B clock generation (internally)
2-) Multiplexing baseband clock input that is applied to REFA pin
(REFA input will be drived with 40MHz clipped sine wave and I want to get 245MHz at the output)
Should I use an external VCXO and apply to VCXO IN?
What should be properties of VCXO?
What frequency range can I apply to this input?
additional explanations for REFA input are added
