AD9363 vs AD9364

Hi,

Although pluto always had a AD9363 on it. Until rev C there where only 1 Rx and 1 Tx channels exposed. AD9364 has only 1 Rx and 1Tx. Frome this comes the association. 
You can extend the range, but to put it nicely, the performance of AD9363 is not guarantied outside the specified interval.

So I understand:

Using two Rx+Tx pairs (1) AND increased frequency range (2) is difficult to achieve on the silicon. AD9364 is based on the same silicon as AD9363 but has gone through additional testing and it does not use two pairs, so (2) is guaranteed.

Even 9363 supports two Rx+Tx pairs, ADALM-PLUTO uses only one Rx+Tx pair anyway, so 9363 can easily be operated in the increased range.

Does that make sense?

Thanks andrei_g

I wouldn't go with "same silicon", hence the specs and the price.
Pluto revC (AD9363) can use 2 RF channel in/out pairs with extended range, but you will not get worse quality compared to an AD9361, going outside the AD9363's specified range.
AD9361 and AD9364 have similar specs, but AD9364 has only 1 RF in/out pair, comparing with the 2 pairs of AD9361.


The AD9364 config was used, back in the days when pluto had only 1 available RF in/out pair.

Oh, I understand that two channels won't give you a worse quality.

So, we cannot say that they have the same silicon. But can we say at least that all AD936{1,3,4} have the same interface? If yes, then at least some part of the silicon must be the same, right?

The interface is the same.

I found another source that claims that AD9363 on the ADALM-PLUTO is just a binned version of AD9364.

> The PlutoSDR (a.k.a. ADALM-PLUTO) is a low-cost SDR made by Analog Devices, based on a binned version of the AD9364 RFIC (same RFIC as in the USRP B200) which AD labels AD9363.
