GigOptix, Inc. (OTCBB:GGOX), today announced the availability for sampling of its GX3122 dual channel linear Transimpedance Amplifier (TIA) designed for use in next generation 40Gb/s DWDM coherent optical receivers.
The GX3122 key features include:
- Two balanced TIA channels in one device to reduce system complexity and cost
- Linear gain over 20dB of dynamic range
- Less than 5% total harmonic distortion (THD)
- Automatic or manual gain control options
- Peak detection function
- Low power consumption
- Receive Strength Signal Indicator
- Form factor compatibility with GigOptix’s 100G dual channel linear TIA solution
The GX3122 TIA consists of two balanced linear 10G TIAs in a single die. The device forms the gain interface between the photodiodes and the Analog to Digital Converters (ADC) and Digital Signal Processor (DSP) in a coherent optical receiver. The GX3122 is designed to have the required large dynamic range and handle the high AC and DC currents with a consistently low THD.
“The GX3122 further expands our TIA portfolio by providing a dedicated solution for the emerging 40G coherent market,” commented Julie Tipton, Vice President Marketing at GigOptix. “The GX3122 is form factor compatible with GigOptix’s 100G DP-QPSK dual channel TIA and this is a major benefit for our customers. It means that receivers designed using our 100G dual channel linear TIA solution for 100G DP-QPSK can now be easily retargeted to 40G DP-QPSK operation using our lower cost GX3122. Similarly, customers who implement a design with our GX3122 can now move more rapidly to a 100G receiver design using our 100G TIA solution. This is a big win for customers who are resourced constrained and are looking to leverage existing engineering designs into new markets.”
40G coherent systems are seen as being a significant segment in future 40G DWDM networks due to the format’s capability for long-haul reach, its high tolerance to signal distortions and its expected OPEX savings over other 40G formats.
