622 Mbit/s SATURN User Network Interface
S/UNI-622
FEATURES
• Monolithic SATURN
®
-compatible
SONET/SDH ATM User Network
Interface (UNI) for LAN, Public UNI, and
Public NNI connections.
• Implements the ATM Transmission
Convergence (TC) sublayer according to
ATM Forum specifications using the
SONET/SDH 622.08 Mbit/s and
155.52 Mbit/s formats.
• Also supports the SONET 51.84 Mbit/s
format.
• Processes all SONET/SDH UNI
overhead.
• Inserts and extracts ATM payloads using
ATM cell delineation.
• Provides a SCI-PHY™-compliant 50 MHz
synchronous 16-bit (4-cell deep) FIFO
buffers in both transmit and receive paths.
• Compatible with ATM Forum UTOPIA
interface format, with support for multi-
PHY applications.
• Provides access to section and line
datalinks and all additional overhead to
allow external processing for full
SONET/SDH Network-Node Interface
(NNI) compliance.
• Provides a generic 8-bit
microprocessor bus interface for
configuration, control, and status
monitoring.
• Provides a standard 5-signal P1149.1
JTAG test port for boundary scan
board test purposes.
• Provides TTL-compatible inputs and
outputs.
• Low power, +5 V CMOS technology.
• Packaged in a 208-pin, 28 mm by
28 mm slugged Plastic Quad Flat Pack
(PQFP) with 0.5 mm pin pitch.
APPLICATIONS
• Workstations and Personal Computer
• LAN Switches and Hubs
• Routers
• Video Servers
• Backbones
• Broadband Switching Systems
• Test Equipment
