ADRV936x RF SOM Hardware

Whether you want to understand the changes between revisions, or just understand how to probe the PCB, this is where all the information should be.

ADRV936x - Mechanical

The ADRV9361-Z7035 SDR 2×2 SOM uses a 20 layer PCB that measures 2.440” x 3.937” (62 mm x 100 mm). The 62mm x 100mm form factor is compatible with the DP10062 “Sick of Beige v1.0” specification from dangerousprototypes.com.

Connectors

The MicroHeaders used on ADRV9361-Z7035 are FCI 0.8mm BergStak®100-position Dual Row, BTB Vertical Receptacles (61082-101400LF). These receptacles mate with any of the FCI 0.8mm BergStak® 100-position Dual Row BTB Vertical Plugs (61083-10x400LF) to provide variable stack heights of 5mm, 6mm, 7mm or 8mm. The SOM uses the FCI “receptacle” while carrier cards use the “plug”. Both receptacle and plug include a PCB locator peg that can be used to design precisely mated SOM and carrier layouts.

Dimensions

The physical dimensions of the connectors, mounting holes and PCB is common between the ADRV9361-Z7035 and the ADRV9364-Z7020.

The Footprint is common between the two parts:

ADRV9361-Z7035 Hardware

Revision F

This is the current shipping version.

  • Changes from Rev E to Rev F:
    • The schematic did not change. We only made an adjustment to the layout.
    • The RF traces were modified to improve the insertion loss and the return loss as well as the EVM.
      • This resulted in some layout changes for discrete capacitors
    • On the SOM the revision is shown as “F2” on the PCB artwork
    • The reset button moved position

Revision E

Revision C (First publicly available revision)

This is the first publicly available revision.

Why do a Rev D?

  • Improved the power structure and increased the 0.95V current from 2A to 6A
  • Added a 1000BASE-KX option for the Ethernet Phy (Ethernet Operation over Electrical Backplanes)
  • Improved the layout to accommodate the power changes.

ADRV9364-Z7020 Hardware

Revision D

This is the current shipping version.

    • There was a small typo in the rev D0 of the schematics (below), the net named *_EN_AGC, was tied to the ENABLE pin, and the net called *_ENABLE was tied to the EN_AGC pin. This is fixed/updated in this schematic. copper/layout does not change, only the designation on the wire (for clarity).
    • This has the notation error described above.

Revision C

This is the first publicly available revision.

Why do a Rev D?

  • Improved the power structure and increased the 1V current from 2A to 4A
    • Improved the layout to accommodate the power changes.
  • Added a 1000BASE-KX option for the Ethernet Phy (Ethernet Operation over Electrical Backplanes)
  • Improved the RF traces to have better insertion loss and return loss.

Carrier Support

The ADRV9361-Z7035 supports all features on the ADRV1CRR-FMC carrier board. The ADRV9364-Z7020 supports a subset of features because the Zynq Z7020 has fewer available user I/Os. For the ADRV9364-Z7020 it is recommended to use the ADRV1CRR-BOB carrier.

Support

Please refer to EngineerZone with questions on hardware/schematics/or using the ADRV936x RF SOMs.
