  Part Number: LMK01020 Hello, LMK01020's data sheet only specifies Θ JA and Θ J-PAD (Thermal Pad) as thermal parameters of the LMK01020, but I don't think that's enough. Could you also provide such thermal parameters as Θ JC …

  Hi Jose, Do you think we could change this setup to a more simple solution by using LMK01020 (first stage) with /4 to get the 25MHz clock and then using a 2:8 LVPECL buffer CDCLVP1208 (second stage) on the first stage outputs ? Since skew in second stage…
