Part Number: LMK00334-Q1
Other Parts Discussed in Thread: LMK00334
Hello team,
Which is the right way for termination in case of oscillator(LVDS)->HCSL->LMK00334-Q1? 
Best regards,
Shotaro Sakai
Hey Shotaro-san, the proper termination is in the image below. To clarify, are you using a HCSL or LP-HCSL receiver for the LVDS driver?
Additionally, are you using another device between the oscillator and the LMK00334? LMK00334 has universal inputs, meaning that an LVDS signal can be DC-coupled to the device as long as the clock passes the input requirements below.
If you are using a true HCSL receiver, make sure to rebias the signal using the below termination network of 470Ω to 3.3V VDD and 56Ω to GND to achieve a common mode of 375mV. If you do not have access to a 3.3V rail, let me know and I can create a network for your available VDD.
If you are using an LP-HCSL receiver, the receiver should rebias the signal automatically, so the termination before the AC coupling and the AC coupling itself are necessary, as shown above.
Thank you,
Tristan
