16-Port, 16-Lane, 80Gbps,
Gen2 RapidIO Switch
CPS-1616
Datasheet
Description
The CPS-1616 (80HCPS1616) is a
RapidIO Specification (Rev. 2.1)
compliant Central 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-1616 supports Serial
RapidIO (S-RIO) packet switching (unicast, multicast, and an optional
broadcast) from any of its 16input ports to any of its 16 output ports.
Features
• RapidIO ports
— 16 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
• I

C Interfaces
— Provides I

C 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
• Switch
— 80 Gbps peak throughput
— Non-blocking data flow architecture
— Configurable for Cut-Through or Store-and-Forward data flow
— Very low latency for all packet lengths and load conditions
— Internal queuing buffer and retransmit buffer
— Standard transmitter- or receiver-controlled flow control
— Global routing or Local Port routing capability
— Supports up to 40 simultaneous multicast masks, with broadcast
— Performance monitoring counters for performance and
diagnostics analysis. Per input port and output port counters
• SerDes
— Transmitter pre-emphasis and drive strength + receiver
equalization provides best possible signal integrity
— Embedded PRBS generation and detection with programmable
polynomials support Bit Error Rate testing
• Additional Information
— 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)

About This Document
Introduction
The
CPS-1616 Datasheet
provides hardware information about the CPS-1616, such as electrical and packaging characteristics. It is intended for
hardware engineers who are designing system interconnect applications with the device.

Document Conventions and Definitions
This document uses the following conventions and definitions:
•
To indicate signal states:
–
Differential signals use the suffix “_P” to indicate the positive half of a differential pair.
–
Differential signals use the suffix “_N” to indicate the negative half of a differential pair.
–
Non-differential signals use the suffix “_N” to indicate an active-low state.
•

•
To define buses, the most significant bit (MSB) is on the left and least significant bit (LSB) is on the right. No leading zeros are included.
To represent numerical values, either decimal, binary, or hexadecimal formats are used. The binary format is as follows: 0bDDD, where “D”
represents either 0 or 1; the hexadecimal format is as follows: 0xDD, where “D” represents the hexadecimal digit(s); otherwise, it is decimal.
Unless otherwise denoted, a byte refers to an 8-bit quantity; a word refers to a 32-bit quantity, and a double word refers to an 8-byte (64-bit)
quantity. This is in accordance with RapidIO convention.
A bit is set when its value is 0b1. A bit is cleared when its value is 0b0.
A read-only register, bit, or field is one that can be read but not modified.
This symbol indicates important configuration information or suggestions.
This symbol indicates procedures or operating levels that may result in misuse or damage to
the device.
