1.11.1. Hardware Setup
- The ADC AD9217 derives power from the FMC pins.
- The field-programmable gate array (FPGA) device clock is supplied by Si5341 clock generator on the development kit.
- Si5341 clock generator provides reference clock to the ADF4355 clock source and FPGA.
- Sampling clock to the ADC AD9217 EVM is given by the external clock source ADF4355.
The following system-level diagram shows how the different modules connect in this design.
In this setup, the data rate of the native PHY transceiver lanes is 5 Gbps. An external clock source card ADF4355 provides sampling clock of 5000 MHz to the ADC (AD9217) through the SMA cables. The Si5341 oscillator on the development kit board provides reference clock to the FPGA and the external clock source board ADF4355. The reference clock to the FPGA is provided to the ATX PLL, which generates the serial clock to transceiver. SPI is used to access the registers in ADC (AD9217).
