Part Number: LMK01010
Other Parts Discussed in Thread: LMK03000, LMK01000

Can both CLKin0 and CLKin1 be driven by 700 MHz single-ended sine wave? What is the recommended termination scheme?

Thank you.

Yes, refer to Figure 12 in the datasheet for this.

Hello Alan,
Are CLKin0 and CLKin1 considered the same as OSCin? May you please clarify this since I do not see OSCin/OSCin* in the Pin Functions on page 3 and 4 in the datasheet.

Per datasheet: The LMK01000 family is footprint compatible with the LMK03000/02000 family of devices. All CLKout pins are

pin-to-pin compatible, and CLKin0 and CLKin1 are equivalent to OSCin and Fin, respectively.

Alan,

Does CLKin0 and CLKin1 support single-ended sine wave input up to 700 MHz? Figure 14. Recommended OSCin Power for Operation with a Sine Wave Input only shows maximum frequency of 100 MHz. If it can be driven by 700 MHz single-ended sine wave, what is the recommended power for Single-Ended Operation at 700 MHz?

Thank you, DH

Yes, input power should be -10 to +5 dBm.
