1 / 48 page  1 of 47 March 31, 2008 DSC 5697 1 Device Overview The CPS-12, device number IDT80KSW0004, is a serial RapidIO (sRIO) switch whose functionality is central to routing packets for distribution among DSPs, processors, FPGAs, other switches, or any other sRIO-based devices. It may also be used in serial RapidIO backplane switching. The CPS-12 supports serial RapidIO packet switching (unicast, multicast, and an optional broadcast) from any of its 12 input ports to any of its 12 output ports. 2 Features ◆ Interfaces - sRIO – 12 bidirectional serial RapidIO (sRIO) lanes v 1.3 – Port Speeds selectable: 3.125Gbps, 2.5Gbps, or 1.25Gbps – All lanes support short haul or long haul reach for each PHY speed – Configurable port count to up to twelve 1x ports, three 4x ports, or combinations of 1x and 4x ports (ex. eight 1x ports and one 4x port) – Lanes can be configured as individual non-redundant 1x ports, as part of a redundant 1x port, or as part of a 4x port – Support for two separate port rates for each quad – Supports standard 4 levels of priority – Error management support ◆ Interfaces - I2C – Provides I2C port for maintenance and error reporting – Master or Slave Operation – Master allows power-on configuration from external ROM – Master mode configuration with external image compressing and checksum ◆ Performance – 30 Gbps of peak switching bandwidth – Non-blocking data flow architecture within each sRIO priority – Very low latency for all packet length and load condition – Internal queuing buffer and retransmit buffer – Standard receiver based physical layer flow control ◆ Features – Configurable for Cut Through or Store And Forward data flow – Device configurable through any of sRIO ports, I2C, or JTAG – Packet Trace. Each port provides the ability to match the first 160 bits of any packet against up to 4 programmable comparison values to copy the packet to a programmable output trace port – Packet Filter. Each port also provides the ability to filter the packet based on comparisons against these same 4 programmable values mentioned above. – Supports up to 10 simultaneous multicast masks – Broadcast support – Port Loopback Debug Feature – Software assisted error recovery, supporting hot swap – Ports may be individually turned off to reduce power – PMON counters for monitor and diagnostics. Per input port and output port counters. – SerDes physical diagnostic registers – Embedded PRBS generation and detection with programmable poly- nomials support Bit Error Rate (BER) testing – 0.13um technology – Low power dissipation – Full JTAG Boundary Scan Support (IEEE1149.1 & 1149.6) – Package: 324-ball grid array, 19mm x 19mm, 1.0mm ball pitch 3 Block Diagram Figure 1 Block diagram Datasheet 80KSW0004 12-Port Serial RapidIO® Switch M a i nt e na nc e & Er r o r M a na ge m en t C o nf i g ur a t i on JT A G I 2 C sR I O E nha nc ed Qu a d ( u p t o 4 po r t s ) sR I O E nha nc ed Qu a d ( u p t o 4 po r t s ) S erial R apidIO S w itch Ln0 Ln1 Ln2 Ln3 Ln4 Ln5 Ln6 Ln7 sR I O E n ha nc ed Qu a d ( u p t o 4 po r t s ) Ln8 Ln9 Ln10 Ln11 |
