Camarillo, CA--April 21, 1997--Vitesse Semiconductor Corp. (Camarillo, CA) announced the availability of the LAB25 Logic Analyzer Board which enables the evaluation of Fibre Channel and Gigabit Ethernet transceivers. The LAB25 Logic Analyzer Board provides a tool for signal quality and performance evaluation of both the VSC7125 Fibre Channel transceiver and the VSC7135 Gigabit Ethernet transceiver.
The LAB25 is a self-contained evaluation unit for testing transceiver characteristics such as output jitter and waveform integrity, as well as basic functionality. In-depth evaluation can be implemented by connecting a pattern generator (10-bits at either 106.25 MHz or 125 MHz) to board pods for transmit data and control signal generation. A logic analyzer can also be connected for monitoring receive data and status signals. In this configuration, 8B/10B encoded data is sent to the evaluation unit's transmitter to generate Fibre Channel/Gigabit Ethernet data which is then monitored by the logic analyzer.
Evaluation board features include a socket architecture for an on-board oscillator. Either the 106.25 oscillator for generation of the VSC7125 transmit clock or the 125 MHz oscillator for generation of the VSC7135 transmit clock can be inserted. Also, an on-board voltage regulator may be used to provide 3.3V to either transceiver. Multiple media choices are supported including either SMA or DSUB-9 connectors to interface with the appropriate test equipment.
The VSC7125 is a 1.0625 Gbps fully integrated 10-bit transceiver. It integrates the transmitter and receiver functions into a single chip and incorporates both clock multiplication and clock recovery using a single, fully integrated PLL. The VSC7135 Gigabit Ethernet transceiver is a derivative of the VSC7125. At 700mW typical power dissipation and 1.25 Gbps data rate, it provides a high-performance and low-power transceiver solution. The VSC7135 is suited for the high bandwidth requirements of the Gigabit Ethernet market.
The VSC7125 is available with the industry standard pinout in the JEDEC 64 pin, 10-mm and 14-mm PQFP packages. The VSC7135 operates of a single +3.3V supply and is available in an industry standard 14-mm PQFP package. Both products are currently in production.
The LAB25 Logic Analyzer Board is currently available and priced at $600.
