S/UNI-ATLAS-1K800

Release

ATM Layer Solution

• Egress input and output interfaces

• Includes a FIFO buffered 16-bit

microprocessor bus interface for cell

insertion and extraction, deterministic

VC Table access, status monitoring

and configuration of the device.

FEATURES

support an 8 or 16 bit SCI-PHY (52 -

64 byte cell) interface using direct

addressing for up to 4 PHY devices

(Utopia Level 1) and Multi-PHY

addressing for up to 32 PHY devices

(Utopia Level 2).

• Monolithic single chip device which

handles bi-directional ATM Layer

functions including VPI/VCI address

translation, cell appending, policing

(ingress only), cell counting and OAM

requirements for 1024 VCs (virtual

connections).

• Supports DMA access for cell

extraction.

• Compatible with the PM7329 S/UNI-

APEX-1K800 Traffic Manager, and

PMC-Sierra’s VORTEX Architecture.

• The UTOPIA and external SRAM

interfaces are 52 MHz max.

• Instantaneous bi-directional transfer

rate of 800 Mbit/s supports a bi-

directional cell transfer rate of

1.42x10⁶cell/s.

POLICING

• Ingress functionality includes a highly

flexible search engine that covers the

entire PHYID/VPI/VCI address range,

dual leaky bucket policing, per-VC cell

counts, OAM-FM and OAM-PM

processing.

• ITU-I.371, ATM Forum TM4.0

compliant, per-VC programmable dual

leaky bucket policing with a

programmable action (tag, discard, or

count only) for each bucket, each with

3 programmable 16 bit non-compliant

cell counts.

• Ingress input interface supports an 8 or

16 bit PHY interface using direct

addressing for up to 4 PHY devices

(Utopia Level 1) and Multi-PHY

addressing for up to 32 PHY devices

(Utopia Level 2).

• Egress functionality includes direct

address lookup, per-VC cell counts,

OAM-FM and OAM-PM processing.

Per-PHY output buffering scheme

resolves the head-of-line blocking

issue.

• Per-PHY single leaky bucket policing

with a programmable action (tag,

discard, or count only).

• Ingress output interface supports an 8

or 16 bit SCI-PHY (52 - 64 byte cell)

interface (Utopia Level 1) to a switch

fabric.
