FEATURES
1.1
General
•
Single chip QUAD ATM User-Network Interface operating at 155.52 Mbit/s.
•
Implements the ATM Forum User Network Interface Specification and the
ATM physical layer for Broadband ISDN according to CCITT
Recommendation I.432.
•
Processes duplex 155.52 Mbit/s STS-3c (STM-1) data streams with on-chip
clock and data recovery and clock synthesis.
•
Exceeds Bellcore GR-253-CORE jitter tolerance and intrinsic jitter criteria.
•
Fully implements the ATM Forum’s Utopia Level 2 Specification with Multi-
PHY addressing and parity support.
•
Provides a standard 5 signal IEEE 1149.1 JTAG test port for boundary scan
board test purposes.
•
Provides a generic 8-bit microprocessor bus interface for configuration,
control, and status monitoring.
•
Low power 3.3V CMOS with PECL and TTL compatible inputs and
CMOS/TTL outputs, with 5V tolerance inputs (system side interface is 3.3V
only).
•
Industrial temperature range (-40
°
C to +85
°
C).
•
304 pin Super BGA package.
1.2
The SONET Receiver
•
Provides a serial interface at 155.52 Mbit/s.
•
Recovers the clock and data.
•
Frames to and de-scrambles the recovered stream.
•
Detects signal degrade (SD) and signal fail (SF) threshold crossing alarms
based on received B2 errors.
