Description

Features

•

RapidIO ports

The CPS-1848 (80HCPS1848) is a RapidIO Specification (Rev. 2.1)

compliant Secure Packet Switch whose functionality is central to

routing packets for distribution among DSPs, processors, FPGAs,

other switches, or any other RapidIO-based devices. It can also be

used in RapidIO backplane switching. The CPS-1848 supports Serial

RapidIO (S-RIO) packet switching (unicast, multicast, and an optional

broadcast) from any of its 18 input ports to any of its 18 output ports.

— 48 bidirectional S-RIO lanes

— Port widths of 1x, 2x, and 4x allow up to 20 Gbps per port

— Port speeds selectable: 6.25, 5, 3.125, 2.5, or 1.25 Gbaud

— Support Level I defined short or long haul reach, and Level II

defined short-, medium-, or long-run reach for each PHY speed

— Error Management Extensions support

— Software-assisted error recovery, supporting hot swap

Additional Information

Defense and aerospace

Video and imaging

— Packet Trace/Mirror. Each input port can copy all incoming

packets matching user-defined criteria to a “trace” output port.

— Packet Filter. Each input port can filter (drop) all incoming packets

matching user-defined criteria.

— Device configurable through any of S-RIO ports, I C, or JTAG

— Full JTAG Boundary Scan Support (IEEE1149.1 and 1149.6)

— Lidless 784-FCBGA Package: 29  29 mm, 1.0 mm ball pitch
