LSI Logic GigaBlaze(R) Cores Support Intel's 'Next Generation I/O' Physical Layer Requirements
MILPITAS, Calif., Nov. 12 /PRNewswire/ -- LSI Logic (NYSE: LSI) announced that its family of GigaBlaze(R) gigabit per second CMOS transceiver cores support the physical requirements of the "Next Generation I/O" (NGIO) architecture, a new input/output initiative proposed by Intel to enable new levels of scalability and reliability for mission critical server platforms.
The GigaBlaze cores meet NGIO's single-speed serial transfer rates of 1.25 Gbits/sec, as well as support the future migration to double-speed data rates of 2.5 Gbits/sec. By combining the power of CMOS integrated transceivers with the ease of use of LSI Logic's CoreWare(R) methodology, the GigaBlaze transceiver cores can be easily integrated into system-level ASICs to implement the new NGIO technology.
A leading provider of high-speed serial interconnects cores for computer and communications companies, LSI Logic has previously integrated multiple GigaBlaze cores with complex logic to form system-level ASICs that played a crucial role in supporting the launch of the Fibre Channel and Gigabit Ethernet markets. These standards utilize the same physical layer techniques that will be used to implement NGIO connections.
"LSI Logic has demonstrated the ability to combine multiple gigabit/sec transceiver cores with ASIC logic," said Mitch Shults, Director of I/O Strategic Marketing at Intel's Enterprise Server Group. "This capability will help enable the rapid development and deployment of cost-effective NGIO host, target, and switch products. We're pleased to have LSI supporting this important program with approaches like the GigaBlaze cores."
The company recently announced a new generation, of GigaBlaze serial interface cores built in its G11(TM) 0.18-micron (Leff) CMOS process to support single-speed data rates of 1.06 and 1.25 Gbits/sec, and double-speed data rates of 2.12 and 2.5 Gbits/sec. The new cores join previous members of the GigaBlaze family, introduced in 1996 and based on the G10(R) 0.25-micron (Leff) process, which offered maximum data rates of 1.25 Gbits/sec.
The GigaBlaze cores provide full duplex, point-to-point communication channels for gigabit serial interfaces. The cores contain both deserializer and serializer circuitry. The deserializer receives a serial, gigabit-speed input data stream and converts it into parallel data. The serializer receives parallel data, converts it into a serialized data stream and transmits this stream at rates from 1.0625 to 2.5 Gbits/sec.
"NGIO is a leading edge, gigabit per second, serial interconnect layer that will span from centimeters to tens of meters," said Marc Miller, Director of Computer Product Marketing at LSI Logic. "Its success requires a semiconductor solution that breaks bandwidth and distance barriers while meeting the low price, power and board real estate requirements of the high volume computer market. Integration of GigaBlaze transceiver cores with logic is an answer to this challenging problem."
