PLLATINUMSIM-SW: Phase Noise over temperature

Daniel Sugimura
Prodigy 150 points
Part Number: PLLATINUMSIM-SW
Other Parts Discussed in Thread: LMX2615-SP, LMK04832-SP, LMK04832

What temperature range is the jitter valid for? Is there a way to adjust the jitter for certain temperatures? I'm specifically targeting LMK04832-SP and LMX2615-SP.

    Hello,

    We are out of office for a US holiday. Please expect a response by Monday.

    Thanks,

    Hi Daniel,

    The database is with typical data at room temperature, we don't have temperature dependent data in the tool. 

    VCO frequency changes with temperature, as a result Vtune will change with temperature. 

    In LMX2615, Kvco changes with Vtune, the variation could be 30 to 40MHz/V. You can use PLL Sim and manually adjust the Kvco to simulation the phase noise variation. 

    In LMK04832, VCO tuning range is relatively narrow, Kvco variation is small, maybe 10MHz/V.
