Find a part on the schematic

Use docs/vendor/7020_936x_SDR-schematic.pdf: 13 pages, created 15 February 2025. Every pin claim in this repository comes from it.

Do not use the vendor's GitHub copy

hardware/schematic_PlutoSky.pdf on the vendor's GitHub is a different board revision: 15 pages, May 2025, no JP5, no 3V3_IO1..4, connectors numbered J1–J12.

Sheet What it settles
1 VCCO_13_1..4 tie to VCC3V3: why bank 13 is LVCMOS33
5 which FPGA ball carries which 3V3_IO net, and which nearby balls are no connect
10 the AD9361 and its 40 MHz reference, Y3
13 connector JP5: which header pin carries which net; GND on pins 2 and 20

Sheet 13 of the vendor schematic, connector JP5, with each 3V3_IO net boxed together with its pin number and the two GND symbols marked

Sheet 13, annotated: the kind of evidence each pin claim rests on. The crops of sheets 1, 5 and 13 are in the GPIO reference.

The main parts

Ref Part Sheet
U1 Xilinx XC7Z020-CLG400: two Cortex-A9 cores plus Artix-7 fabric 1, 2, 3, 5, 6
U2 U3 Micron MT41K256M16TW-107IT:P, DDR3L: 1 GB together 3
U11 Analog Devices AD9361: 2×2 transceiver, 70 MHz – 6 GHz 10, 11, 12
U12 U13 Mini-Circuits PGA-102+: transmit power amplifier, one per channel 12
T1–T4 RF baluns (no part number): they set the usable frequency range 12

IC2 Realtek RTL8211F-CG: gigabit Ethernet PHY 4

The ratings everything is checked against

AD9361 Data Sheet, Rev. G, Table 11
RF Inputs (Peak Power) 2.5 dBm: nothing may reach a receive input above this
Maximum Junction Temperature 110 °C (150 °C is the storage maximum, a different row)
