Introduction
The AD9144-FMC-EBZ connects to an ADS7 data pattern generator system. The AD9144 is a quad
JESD204B signal processing RF Digital to Analog Converter. The ADS7 automatically formats the data
and sends it to the AD9144-FMC-EBZ via its JESD204B lanes. The AD9144-FMC-EBZ is an FMC
mezzanine card. +12V, +3.3V, and VADJ power supply rails are provided by the ADS7 system via the
FMC connector P1. A clock distribution chip AD9516 is included on this EVB as a clock fan-out and
frequency divider for the DACCLK, JESD204B SYSREF signals, and a GBTCLK clock used by the ADS7.
There is also an FMC standard I2C bus that is used by the ADS7 to identify the AD9144-FMC-EBZ. This
I2C interface is implemented in software in the AD9144-FMC-EBZ PIC processor (XU1). All ADS7
to/from AD9144-FMC-EBZ interface signals are connected via the FMC connector P1.
