Hello,

 

Could you asvise me how to improve the delay skew of IF output for using multiple HMC1190LP6GEs?

 

Our customer is using four HMC1190LP6GEs on a board, and maximu delay skew among IF outputs is 4.7ns. The customer would like to improve the delat skew to 1.0ns or less. Do you have any ideas for improving the delay skew?

 

Reference Frequency : 10MHz  Square wave

Exact Frequency Mode : enable (Reg 06h bit[5] = 1

Phase Sync : enable (Reg 14h bit[9] = 1

Length of RF and IF signal lines on a PCB are same.

 

Best regards,

Akira
