I think that HMC1010, HMC1020 and HMC909 is a pin compatible devices.
Is that right?
Thanks for your reply.
I found out the pin compatible information between HMC909 and HMC1010 in the posted inquiry as below.
Therefore, I thought that Pin24 of HMC909 could be connected to GND since it is not connected internally.
Is there any wrong on the my thought above ?
