We are in PCB layout stage and there are questions need your advise on ADMV1013+ADF5610 soon.
1. Routing issue: If we connect ADF5610 28Pin (PDIV_OUT)/27Pin(NDIV_OUT) to ADMV1013 38Pin(LOP)/37Pin(LON), we met a problem that the trace will crossover, for real connection may I connect P to N (PDIV_out connect to LON), N to P(NDIV_OUT connect to LOP) to prevent trace crossover?
2. About the reference layout of EV-ADF5610SD1Z Pin28 and Pin27, there are some GND VIA between the two trace. I think its for EVB evaluate purpose.
If we design for end product, the two trace should be placed together without GND VIA between the two trace, directly connect to IC, am I right?
Sorry for my poor expression, please let me know if anything needs to clarify.
For 1: This shouldn't be an issue for the ADMV1013.
For the ADMV1013 the eval board has single ended traces for the LO path in case the user wants to drive the LO single ended vs differential.
Thank you for the reply
According to ADF5610 functional block diagram, single-end RF output only for LO x1, x2 function. but if we need (divided by 1, 2, 4, 8, 16, 32, 64, 128) function, the connection must be differential. Could you advise if we can connect P to N, N to P?
Sorry since this schedule is urgent, sincerely wait for your feedback.
As I previously stated switching the P and N into LO for the ADMV1013 will not be an issue for the ADMV1013.
Noted, thank you!
