GigOptix launches TIA portfolio for 10G, 40G and 100G

GigOptix Inc of Palo Alto, CA, USA, which designs optical modulators, drivers and transimpedance amplifier (TIA) ICs based on III-V materials, has made available samples of a complete family of TIAs that enables it to address all major 10Gb/s, 40Gb/s and 100Gb/s receiver applications.

The new family includes:

  • GX3101, a high-gain limiting TIA for 10.3Gb/s Ethernet whose large dynamic range enables it to support all existing 10G Ethernet optical reaches (simplifying logistics by having one part spanning all reaches);
  • GX3110, a linear TIA with automatic gain control (AGC) for 11.3Gb/s SONET whose total harmonic distortion figure is superior to current solutions on the market, it is claimed, enabling customers to improve product performance;
  • GX3200, a limiting TIA for 100GBASE-LR4/ER4 receiver designs whose low power and compact form suit next-generation 100G Ethernet solutions; and
  • GX3220, a balanced linear TIA with AGC whose bandwidth control function enables it to address the emerging 40G DQPSK (differential quadrature phase-shift keying) and 100G DP-QPSK (dual-polarization quadrature phase-shift keying)receiver markets.

The new family strengthens GigOptix’s portfolio of TIA solutions, which already includes the GX3440, which addresses the OC-768 40G DPSK (differential phase-shift keying) market, and the ultra-low-power HXR4104 and HXR4112 TIA array products, which address Infiniband QDR (quad data rate) and emerging 40GBASE-SR4/LR4 and 100G-BASE-SR10 100G Ethernet standards.

“We are greatly expanding our addressable market and balancing our strong driver portfolio with an equally attractive and complete set of products for the receive side,” says VP of marketing Julie Tipton. “This complete portfolio has been driven by our customers seeking better solutions than those currently available in the market. The opportunities are tremendous as there are few companies delivering these challenging designs,” she adds.

“These demanding new designs were possible due to the close collaboration between the GigOptix-Helix team in Zurich and the high-speed design team in Palo Alto,” says Joerg Wieland, VP & general manager of Swiss subsidiary GigOptix-Helix (acquired in January 2008). “We were able to blend the skill sets of both design groups... This demonstrates our successful and synergistic integration of the two entities under the GigOptix umbrella,” he adds.

According to Ovum’s Q209 Telecom and Datacom forecast, the annual total available market for this family of products is 8.8 million units in 2009 and should grow to 35 million units by 2014.
