Product overview
Arbitrary Broadband Signal Generation L and S bands, Automatic Test Equipment (ATE)
The AF207 is part of ApisSys’ range of modular IOs solutions based on the VITA 57, FPGA Mezzanine Card standard.
The AF207 provides customers with a dual channel 14-bit up to 2.8 Gsps DAC capability, ideally suited for test and measurement, Software Defined Radio or Radar Transmitter applications.
The AF207 DAC channels are AC coupled with an output bandwidth wider than 5 GHz for a full scale signal of -4 dBm (400 mVpp).
The AF207 provides an internal ultra-low jitter clock generation and can be used with either an external clock or an external reference for higher flexibility.
The AF207 features an external trigger input and an external trigger output used to synchronize processing with external events.
The AF207 is fully supported on ApisSys 3U VPX FPGA processing engines.

Description
14-bit 2.8 GSPS DACs
The AF2074 Digital to Analog conversion is performed by two Analog Devices AD9129 14-bit 2.8 Gsps DAC.The DACs can be used with x2 interpolator for improved performances with 5.6 Gsps DAC update rate.The AF207 provides two front panel SSMC connectors for the analog outputs.The output signal is single ended AC coupled with an output bandwidth from 1 MHz to more than 5 GHz with -4 dBm output level.
Clock
The AF207 provides an internal ultra low jitter clock generator locked on a 100 MHz internal reference.The AF207 provides a front panel SSMC connector for an external reference from 10 to 100 MHz, a front panel SSMC connector for an external clock input from 500 MHz to 2.8 GHz.Estimated jitter from the internal clock generation (including 100 MHz reference and clock distribution) is below 200 fs for a 2.8 GHz clock. Added jitter on external clock is lower than 100 fs.
Trigger and Synchronization
The AF207 provides a front panel SSMC connector for an external trigger input and one front panel SSMC connector for an external trigger output.The trigger input and output signals are buffered with ultrafast PECL buffers.
FMC interface
The AF207 features a VITA 57 – FMC (FPGA Mezzanine Card) compliant interface.The FMC uses High Pin Count (HPC) interface with 1.8V or 2.5V Vadj.The FMC MGT interfaces are unused.
Firmware
The AF207 comes with a firmware package which includes VHDL cores allowing control and communication with all AF207 hardware resources.A base design is provided which demonstrates the use of the AF207 and gives users a starting point for firmware development.The AF207 firmware package is supported on the Xilinx ISE® 14 and VIVADO 2014.2 design suites and later versions.The AF207 firmware package has been fully validated on AV108 and other ApisSys FMC carrier products.
Software
The AF207 is delivered with a control software compatible with AV108 and other ApisSys FMC carrier products.An application example is provided as source code.
Ruggedization
The AF207 is delivered in air cooled and conduction cooled standard or rugged versions for use in severe environmental conditions.Standard VITA 47 supported ruggedization levels are EAC4, EAC6 and ECC3.
