GigPeak samples low-power-consumption 32Gbps dual-channel linear coherent TIA

GigPeak Inc of San Jose, CA, USA (formerly GigOptix), which provides integrated circuits and software solutions for high-speed connectivity and high-quality video compression over the network and the cloud, has announced the availability for wider-base customer sampling of its GX32222, a 32Gbps dual-channel linear trans-impedance amplifier (TIA)/variable-gain amplifier (VGA) designed for use in 100-200Gbps DWDM optical receivers used for both long-haul and metro telecom applications. This fundamental TIA design enables its use in a number of currently deployed fiber-optic receiver modules of 100Gbps and 200Gbps coherent optical systems, as well as future 400Gbps-and-beyond applications. The GX32222 is now available for general sampling, after completion of initial sampling by selected customers.

GigPeak claims that the GX32222 TIA offers low power consumption and a cost advantage compared with competing solutions for the ever-growing 100G metro and long-haul WDM applications. Market research firm Ovum projects that those 100G port shipments will continue to increase with an accelerated compound annual growth rate (CAGR) of 25-30% to 2020, while being augmented with the next generations of higher-speed coherent single-wavelength solutions, for both line-cards and pluggable modules.

"The introduction of this product substantiates our already well accepted GPPO connectorized and SMT drivers for 100Gbps and 200Gbps applications, allowing us to provide our customers with ICs for transmit and receive applications," says Dr Koichi Murata, senior director of marketing for Telecom Products.

Key features of the GX32222 TIA include: an adjusted frequency range (supporting 28-32Gbps); low power consumption of 515mW at 3.3V; differential gain >7000 ohm; linear gain over 30dB of dynamic range; and features such as internal AGC (automatic gain control), output voltage control, peak detection, shutdown mode, and BW adjustment.
