I'm using the HMC-493 (divide by 4) and the HMC-492 (divide by 2) in an application such that they don't always have RF applied to their input. I've just read the app note "Frequency Divider Operation and Compensation with no input signal" and understand the need for a shunt resistor on the complementary input pin to ground.
The document lists suggested values for this shunt resistors for several dividers however, the HMC-493 and HMC-492 isn't included in the list. I'm curious to know if Analog Devices/Hittite has a recommended value for said shunt resistor for these two devices?
In the past we have found that 8.25k was the appropriate value to prevent self oscillation without RF input for the HMC492, HMC493, and HMC494.
