LMK01020: Datasheet Inquiry

Part Number: LMK01020

Hi E2E,

Good day. 

Need your assistance with regards to the following inquiries from the customer regarding LMK01020:

  1. Specifications for the clock input signal:
    1.1 Does it has to be an AC signal?
    1.2 Does it have to be something like LVDS?
    1.3 They wish to supply a very clean clock at 41MHz, that is a sinewave. Do they have to convert to LVDS. or something before connecting to LMK01020?
    1.4 The clock signal level is spec'ed in dBm, which suggests a sinewave. However it looks like
    they need a square wave to follow slew rate spec, so dBm (power) makes no sense because the power is divided into harmonics. What is the voltage level if they have a square wave clock?
  2. The lowest clock freq allowed is 1MHz. If it is a sinewave, then they violate the minimum slew rate spec. What happens if we violate the minimum slew rate spec?
  3. Do you have suggestion on how to supply an external sinewave to LMK01020? They are considering LTC6957-1 or 2. Is there an appropriate equivalent TI part suitable for this function? They are going to use this to convert sinewave to square wave.

Thanks in advance!

Best Regards,
