DUAL SERIAL LINK PHY MULTIPLEXER

PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE

FEATURES

• Integrated analog/digital device that interfaces a high-speed parallel bus to a

high speed Low Voltage Differential Signal (LVDS) serial link with optional 1:1

protection.

• For framers or modems without Utopia bus interfaces the S/UNI-DUPLEX

provides cell delineation (I.432) across 16 clock and data (bit serial)

interfaces.

• Fault detection, redundancy, protection switching, and inserting/removing

cards while the system is running (hot swap).

• Interface to other S/UNI-DUPLEX or S/UNI-VORTEX, to satisfy a full set of

system level requirements for backplane interconnect:

• Transports user data by providing the inter-card data-path.

• Inter-processor communication by providing an integrated inter-card

control channel.

• Exchanges flow control information (back-pressure) to prevent data

loss.

• Provides embedded command and control signals across the

backplane: system reset, error indications, protection switching

commands, etc.

• Clock/timing distribution (system clocks as well as reference clocks

such as 8 kHz timing references).

• When used as a parallel bus slave device, can be configured to share the

bus with other S/UNI-DUPLEX bus slave devices.

• Can interface to another S/UNI-DUPLEX device (via a single LVDS link) to

create a simple point-to-point "Utopia bus extension" capability.

• Can interface to two S/UNI-DUPLEX devices to create a 1:1 protected bus

extension.

• Interworks with PM7351 S/UNI-VORTEX devices to implement a point-to-

multipoint serial backplane architecture, with optional 1:1 protection of the

common card.

• In the LVDS receive direction: selects traffic from the LVDS link marked active

and demultiplexes the individual cell streams to the appropriate PHY device.
