• Each chip supports the EXACT Bus Protocol, which is a 10-bit, unidirectional insertion ring running at 125 MHz or 135 MHz. • EXACT Bus ports allow simple box-tobox, card-to-card, or chip-to-chip interconnect. • 8B/10B EXACT Bus encoding is compatible with Common Serialization (SERDES) devices to allow serial extension using coax or twinax cable. • Management interface connects to an off-chip microprocessor for access to internal control registers.
Octal EXACT™ Bus Switch Matrix
FEATURES
• Sixteen Gbit/s, protocol-independent switching matrix expandable to 32 Gbit/s. • Provides eight gigabit, full-duplex EXACT™ Bus ports that each support an EXACT switch port controller.
