Analog Devices ADRV9371-W/PCBZ Development Board
The Critical Link MitySOM-A10S Development Kit is comprised of 2 boards, a SOM and a carrier board. The MitySOM-A10S SOM plugs into the carrier board via 2 connectors, a hirose 144-pin, and a VITA-57 HPC FMC connector.
The major components of the Critical Link MitySOM-A10S Development Kit are identified by numbers:
Ethernet RJ-45 interface
USB-OTG interface
USB-serial interface
FMC loopback interfaces supporting gigabit transceivers, LVDS and single-ended I/Os
PCIe x8 edge connector (optional). Dev kit with this option P/N: 80-001181
Power management
The Critical Link MitySOM-A10S system on a module featuring the Intel Arria 10 SoC (system on a chip) with dual core Arm® Cortex® A9 32-bit RISC processors is a highly-configurable, medium-form-factor module. In addition to the processor, the module includes on-board power supplies, two DDR4 RAM memory subsystems, optional eMMC, micro SD card, a fan controller, RTC, a USB 2.0 on the go (OTG) port, and a temperature sensor. The MitySOM-A10S provides a complete and flexible CPU infrastructure for highly integrated embedded systems.

- 1x Sniffer Receiver Path Input
- JESD204B digital interface
AD7291 - 8-Channel, I2C, 12-Bit SAR ADC with Temperature Sensor
EEPROM - Board ID
AD9528 - JESD204B Clock Generator with 14 LVDS/HSTL Outputs
VCXO - 122.8MHz VCXO
ADP5054 - Quad Buck Regulator PMIC
The develpment boardcomes with:
- Two 8GB SD cards:
- One for Linux driver and IIO Scope (AD-FMC-SDCARD)
- One for Windows-based GUI (ADRV9371-SDCARD)
The block diagram of the ADRV9371-W/PCBZ Eval board (below) shows the major components. The clock is being sourced from the onboard 122.88MHz voltage controller crystal oscillator feeding the AD9528 JESD204B clock generator which provides all of the clocks to both the AD9371 module and the FMC connector, where it will route to the Critical Link MitySOM A10S. Also shown is the ADP5054 quad buck regulator integrated power solution powered by the FMC connector, the AD7291 8-channel, 12-bit SAR voltage sensor, and the hi-speed RX and Tx links connecting from the AD9371 to the FMC connector.
