PM7350

S/UNI-DUPLEX

PMC-Sierra,Inc.

Dual Serial Link, PHY Multiplexer

• 160 ball PBGA, 15mm x 15mm.

• 8/16 bit, 52 MHz extended UTOPIA L2

bus slave (compatible with PM7351

S/UNI-VORTEX).

• 16 port, 4 pin clocked serial data

interface (Tx & Rx), with integrated

I.432 ATM cell delineation.

FEATURES

• In the LVDS receive direction: selects

traffic from the LVDS link marked

active and demultiplexes the individual

cell streams to the appropriate PHY

device.

• In the LVDS transmit direction: accepts

52-56 byte cell streams from up to 32

UTOPIA L2 compatible PHY devices,

multiplexing into a single cell stream

carried over two high speed LVDS

serial interfaces.

• Cell read/write to both LVDS links

available through the processor port.

Provides optional hardware assisted

CRC32 calculation across cells to

support an embedded inter-processor

communication channel across the

LVDS links.

• Integrated analog/digital device that

interfaces a UTOPIA L2 bus to a serial

backplane with optional 1:1 protection

using high speed Low Voltage

Differential Signal (LVDS) serial links.

• For framers or modems without

UTOPIA bus interfaces: optionally

provides cell delineation (I.432) across

16 clock and data (bit serial)

LVDS INTERFACES

• Dual 4 wire LVDS serial transceivers

each operating at up to 200 Mb/s.

• Operates across PCB or backplane

traces, or across up to 10 meters of 4

wire twisted pair cabling for inter-shelf

communications.

• Fully integrated LVDS clock synthesis

and recovery. No external analog

components are required.

interfaces.

• 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.

• Interfaces to another S/UNI-DUPLEX

device (via a single LVDS link) to

create a simple point-to-point “UTOPIA

bus extension” capability.

• Usable bandwidth (excludes system

overhead) of 186 Mb/s.

LVDS TRANSMIT DIRECTION

PHY/FRAMER INTERFACES

• Interfaces to two S/UNI-DUPLEX

devices to create a 1:1 protected bus

extension.

• Requires no external memory devices.

• Low power 3.3V CMOS technology.

• Standard 5 pin P1149 JTAG port.

• Simple round-robin multiplex of up to

32 PHYs (or 16 clock/data interfaces)

plus the microprocessor port’s cell

transfer buffer.

• Multiplexed cell stream broadcast to

both LVDS simultaneously.

One of three modes can be selected:

• 8/16 bit, 33 MHz UTOPIA L2 bus

master (also supports expanded length

cells).
