GigOptix, Inc., is making available samples of its newest GNSS RF receiver for road, maritime, agriculture and surveying applications.

GigOptrix is a supplier of advanced high speed semiconductor components for use in long-haul, metro, cloud connectivity, data centers, consumer electronics links and interactive applications, through optical and wireless communications networks.

The new EXG0201 device is expected to be one of several RF-focused products the company will bring to market over the next few quarters stemming from the recently acquired Tahoe RF Semiconductor, now called the GigOptix-Auburn RF Design Center after its integration into GigOptix earlier this month.

The new EXG0201 product marks the introduction of GNSS RF receivers by GigOptix. It is a low-power consumption, highly linear RF GNSS receiver in a small Quad Flat No-Lead (QFN) package. The fully integrated device is optimized for industrial applications and has dual channels supporting both the upper and lower GNSS bands.

The EXG0201 provides two modes of operation, a high-resolution mode and a low-resolution, low-power mode. It integrates RF signal processing, 12 or 3-bit analog to digital convertors, dual fractional-N synthesizers (with a shared reference to generate RF LO signals) and a three-wire SPI digital interface to provide the necessary functionality required to create a high-end GNSS receiver system. All of the EXG0201 sub-systems are programmable through the use of the on-chip SPI interface.

The GNSS industrial market, supporting road, maritime, agriculture, and surveying applications, is expected to grow to 67% in annual shipments to 43 million devices. The road segment dominates the annual quantity consuming about 98% of the total shipments. The road segment’s growth is driven by increased regulatory pressure for E911 emergency location calls.

“The EXG0201 represents our introduction of fully integrated RF-to-bits devices into a growing GNSS market, and serves as a proof point to the strategic importance of the Tahoe RF acquisition. The newly acquired IP and product capabilities put us in an excellent position to provide differentiated solutions and increased business over the long-term,” said Irshad Rasheed, director of marketing for wireless and RF products at GigOptix. “From a capabilities standpoint, the EXG0201 provides excellent performance with 28 MHz of signal bandwidth, dual-channel operation, 60 dB of instantaneous dynamic range, and 75 dB of gain, all contained within a small 72-pin QFN package.”

The EXG0201 is expected to ship in full production quantities starting in the fourth quarter of fiscal 2014.
