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