PM3390  
Octal EXACT™ Bus Switch Matrix  
• Each chip supports the EXACT Bus  
Protocol, which is a 10-bit,  
PACKAGING  
FEATURES  
• Provides a standard five signal  
P1149.1 JTAG test port for boundary  
scan board test purposes.  
• Implemented in low power 3.3 V,  
CMOS technology.  
• 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  
unidirectional insertion ring running at  
125 MHz or 135 MHz.  
• EXACT Bus ports allow simple box-to-  
box, 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.  
• Available in a 352-pin Ball Grid Array  
(BGA) package.  
APPLICATIONS  
• High Bandwidth (16 to 32 Gbit/s)  
Ethernet Switches that Support  
Combinations of 10/100/1000 Ports.  
• Multiprotocol Switch (Ethernet, ATM,  
Packet Over SONET, FDDI, and TR)  
• Modular Ethernet Switches.  
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 lookup table maps logical  
EXACT ports to physical PM3390 ports.  
Destination lookup table can be

• Interworks with the following EXACT  
Chipset devices:  
• Fixed-configuration Ethernet Switches.  
dynamically allocated.  
PM3370 Octal 10/100 Ethernet Switch  
Port Controller with MII interfaces.  
• Provides visibility into internal dataflow to  
allow external flow control in systems that  
do not use the EXACT Bus link protocol.
