MILPITAS, Calif. -- BitBlitz Communications Inc. here this week will launch an eight-channel part that incorporates the low-power CMOS technology the company unveiled last summer. The BBT3800 transceiver has eight data channels running at 3.125 Gbits per second each. Power consumption is 200 mW/channel.
The relatively low power budget is important because of the increasing port densities in routers and switches, said Leo Wong, director of strategic marketing for BitBlitz "You can find thousands of serializer/deserializers in these boxes," he said.
The chip expands the clock-and-data recovery technology that BitBlitz unveiled in June (see June 26 story). That technology, used by each channel to receive data, is now surrounded by the mixed-signal circuitry needed for a full transceiver. It puts BitBlitz into new markets, Wong said, including serial backplanes and, perhaps, 10-Gigabit Ethernet. For the latter the BBT3800 can operate in two groups of four channels, communicating with two 10-Gbit/s Ethernet ports over the XAUI bus.
Based on a BitBlitz CMOS technology called large-amplitude differential logic, the chip is due to sample in January at $135 each in lots of 1,000. A four-channel version, the BBT3400, is sampling now priced at $70 apiece.
