Other Parts Discussed in Thread: LMH2191, CDC3RL02
Hi i use a TXCO 52MHz with 2 clock buffer LMH2191.
TCXO with no load is ok. If i connect LMH2191 on TXCO output, 52Mhz clock amplitude is divided by 2.
I try to insert in serie 1nF between TXCO output and buffer input, but same result.
I don't understand why clock buffer decreases TXCO output.
My TCXO recommend 1nF output ac coupling. Outputs buffer have no load at all.
Can you help me on this subject?
Do you have an eval board sample to send me?
Best regards,
Céline
