FEATURES
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).
Instantaneous bi-directional transfer
rate of 800 Mbit/s supports a bi-
directional cell transfer rate of
1.42x10
6
cell/s.
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).
Ingress output interface supports an 8
or 16 bit SCI-PHY (52 - 64 byte cell)
interface (Utopia Level 1) to a switch
fabric.
Egress input and output interfaces
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).
Compatible with the PM7329 S/UNI-
APEX-1K800 Traffic Manager, and
PMC-Sierra’s VORTEX Architecture.
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.
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.
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.
Supports DMA access for cell
extraction.
The UTOPIA and external SRAM
interfaces are 52 MHz max.
POLICING
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.
Per-PHY single leaky bucket policing
with a programmable action (tag,
discard, or count only).
