Overview
The HSA module was designed for developing new wireless/digital
radio systems using advances in analog converters and
FPGA devices. With its high-speed, high-resolution and
large, reconfigurable logic, the applications are limitless.
Two analog input channels using AD6644 A/D converters
provide signal capture on 50ohm impedance with 14-bit
resolution at up to 65MSPS, with 7th order on-board
anti-alias filtering. Clocking is provided with an AD9852
DDS and 5ppm TCXO. Digital output are buffered in FIFOs
within FPGA. Two AD9764 D/A capable of 80MSPS deliver
analog signal into smoothing filters and output buffer
amp for +/-1V output matched to 50ohm. The Omnibus interface
allows 32-bit communication with the host DSP board
with sustained data rate of 6-8 MHz.
Firmware source code is provided, implementing peripheral
controls, Omnibus interface and demonstrating bi-directional
data flow, and is a solid framework for advanced developers
using the HSA for hardware-assisted signal processing
systems.
