Objectives
The goal of this activity was to design, manufacture and demonstrate two hybrid devices encompassing: an ADC with an electro-optic transmitter and a DAC with an optoelectronic receiver both adapted to support Gbps fibre optic interconnects linking to a high throughput Digital Signal Processor on board telecommunications satellites.
Challenges
The key issue of this project is to develop two hybrid devices encompassing:
- State-of-the-art AD-Converter with an electro-optic transmitter,
- State-of-the-art DA-Converter with an optoelectronic receiver.
The main challenges were in the realisation of opto-electronic sub-assembles and combining them with a SERDES function realized using an FPGA circuit with output ports operating at 6.25 Gbps. The link contains 4 parallel channels and is redundant.
Plan
Specific tasks to be performed in this project are the following:
- Review of requirements and architectural Trade-off,
- Design, manufacture and testing of Hybrid ADC device,
- Design, manufacture and testing of Hybrid DAC device.
Current Status
The project was completed at the end of June, 2012.
