LMK00301: support Lvpecl frequency

Part Number: LMK00301

Hi Team,

If LMK00301 can support input/output LVPECL signal frequency below 0.75Ghz?

What's the meaning of the  Fclkout_fs  and Fas below?  why the min output freq is 1Ghz?  But the test data show the output freq at 100Mhz?

  • Hi Lilian,

    Apologize for the spec being a little confusing. What the spec is telling you is that for guaranteed VOD >= 600mV, what the (minimum) Max output frequency will be. So basically VOD >= 600mV, is guaranteed for output frequencies >= 1 GHz at Vcco=3.3V, with the recommended termination. LVPECL outputs operate from DC - 3.1 GHz (@ 3.3V supply)
