Fourth Generation High Performance Multi-Gigabit/s CMOS Transceiver Cores
Overview
LSI Logic鈥檚 GigaBlaze cores are the first multi-gigabit per second CMOS transceiver
cores in the industry. They provide a full-duplex, point-to-point communications
channel for gigabit speed serial interfaces. Protocol independence enables the
cores to be used with standard high-speed communications protocols to create a
high-speed serial interface. Applications for the cores include storage subsystems,
network switches and routers, System Area Networks (SAN) and high-speed
backplanes.
The GigaBlaze cores are optimally designed for use as a physical layer for high-
speed protocols including InfiniBand, 10 Gigabit Ethernet, and Fibre Channel
standards. Multiple GigaBlaze cores can be integrated into a single ASIC.
Combined with other LSI Logic standards-based cores, such as Merlin鈩?Fibre
Channel, the TinyRISC鈩?and MiniRISC鈩?processors, and PCI, the GigaBlaze
core enables a completely new approach to high-performance, single-chip solution
for increased differentiation and reduced chip count, power and cost. The fourth
generation GigaBlaze transceiver is now available in LSI Logic鈥檚 G12鈩?process
technology, along with the G11鈩? G10
廬
and 500K process technologies as
shown in Figure 1 below. GigaBlaze technology is also used in LSI Logic鈥檚
SpeedBlazer鈩?family of standard product transceivers.
Description
The GigaBlaze core consists of deserializer and serializer pattern and alignment
circuitry. The deserializer receives a serial gigabit speed input encoded data
stream and converts it into parallel data. This parallel data acts as an input for
any high-speed protocol handler. Likewise, encoded parallel data from the
protocol handler can be transmitted at gigabit speeds after being converted into a
serial stream by the serializer.
