Dear Sir

Please can you recommend a loop filter circuit for an HMC698 PLL chip and an HMC586 VCO with a feedback divider ratio of 12 and a PFD frequency of 500MHz, optimised for best integrated phase noise, integrated over 10kHz to 20MHz? Preferably using a Texas Instruments OPA211 op amp in the loop filter?

Or better still provide a version of ADIsimPLL that models the HMC698?

Thanks

JP
