GigOptix Introduces Linear TIA for 40G Coherent Receivers
The GX3122 key features include:
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.
The GX3122 is now sampling. Sample requests can be ordered by calling our sales team on 1-888-XOX-GIGX or emailing sales@gigoptix.com.
