Advance

PM5390 S/UNI®-9953

• Provides egress Ethernet frame

encapsulation (pads to min. size, add

preamble, IFG and CRC generation).

• Supports VLAN tagged frames.

• Provides eight exact-match address

filters to filter frames based on SA, DA

or VID.

• Provides 64-bin hash based algorithm

to filter multicast addresses.

• Minimum frame size of 64 bytes.

• Provides statistics counters to support

RMON/SNMP.

• Supports jumbo frames up to

9.6 Kbytes.

• Programmable inter-packet gap (IPG).

• Implements in-band PAUSE flow-

control and provides support for out-of-

band flow control.

• Upper layer device can flow-control

using dedicated pins or host signaling

to cause generation of a PAUSE

frame.

GENERAL

• Provides internal FIFOs (16 KB

ingress, 20 KB egress) to

accommodate system latencies.

• Provides line-side and system-side

loopbacks for system level diagnostic

capability.

• Provides support for automatic

protection switching (APS) via two 16-

bit LVDS 777.76 MHz ports.

• Provides a generic 16-bit

microprocessor bus interface for

configuration, control, and status

monitoring.

• Standard 5 signal P1149.1 JTAG test

port.

• Low power 1.8 V CMOS core logic with

3.3 V CMOS/TTL compatible digital

inputs and digital outputs.

• Industrial temperature range (-40 °C to

+85 °C).

• 1152 pin FCBGA package.

DEVICE INTERWORKING

• Other PMC-Sierra devices that

implement the POS-PHY Level 4

interface include:

•

S/UNI 1x10GE.

•

S/UNI 10xGE.

•

S/UNI 9953-POS.

POS-PHY LEVEL 4 INTERFACE

• Designed to transmit cells, packets or

frames between physical and data-link

layer devices.

• Supports mixed traffic protocols on a

channel by channel basis.

• Requires less pins and draws less

power than other 10 Gigabit interface

options.

• Compliant with the following

standards:

•

Optical Internetworking Forum -

System Physical Interface Level 4

Phase II (SPI-4 Phase II).

•

ATM Forum - Frame Based ATM

Interface Level 4 (ATMF0161.00).

•

SATURN® POS-PHY™ Level 4,

Issue 6, March 2001.

APPLICATIONS
