PM3390 - Octal EXACT Bus Switch Matrix

Download the PM3390 datasheet PDF. This datasheet also covers the PM3390_PMC variant, as both devices belong to the same octal exact bus switch matrix family and are provided as variant models within a single manufacturer datasheet.

Key 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.
  • Provides non-blocking connection between eight EXACT Bus (Ethernet Switching, Access, Control, and Termination) rings.
  • Supports non-blocking connections between sixteen EXACT Bus rings to provide a system bandwidth of 32 Gbit/s using four PM3390 devices.
  • Destination.

PMC-Sierra,Inc. PM3390 • 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.
