GTB1684

GuldeTech GTB1684 14.5Gbps Quad PBERG device with multiple coaxial and BNC connectors

GTB1684

The GTB1684 is a light weight, high quality 14.5Gbps, 4-Channel BERT system. It is the ideal choice for high speed serial bus testing.

Accurate testing at today’s high speed serial links requires the test tool to generate very clean signals with the lowest jitter possible. The GTB1684’s fast rise time, low noise and low jitter are evident in the high fidelity output eye on all four channels.

On the detector side the GTB1684 is equipped with flexible and independent receivers on each channel, each with its own high quality equalizer and CDR.

Traditional BERT systems are hard to operate; the GTB1684’s GUI was designed specifically to simplify the test setup and to quickly get results. It takes a few seconds from power-up to the point when the user sees test results.

The GTB1684 offers fully differential I/Os, adjusted amplitude levels, and independent PRBS patterns on all output channels. On the input side it offers auto-lock CDR and programmable equalizer.

Applications

The GTB1684 is an ideal and affordable choice for R&D labs, optical transceiver production line, and silicon testing among many other applications. The affordability of the GTB1684 makes sense in the R&D environment, as most times standard tools are too pricey and there’s no real need for each and every corner-case control.

The multiple channel configurations allow the user to test backplanes, ICs, and electrical & optical transceivers on multiple channels, test for crosstalk and other sensitivities which related to multi-channel design.

The GTB1684’s clean and stable clock source allows for easy characterization of maximum data rates up to 14.5 Gbps. The many divide ratios on the clock’s circuit output allows for easy external triggering of sampling scopes.
