FEATURES
1.1
General
•
•
Single chip ATM and POS User-Network Interface operating at 2488.32 Mbit/s.
Implements the ATM Forum User Network Interface Specification and the ATM physical layer for
Broadband ISDN according to CCITT Recommendation I.432.
•
•
Implements the Point-to-Point Protocol (PPP) over SONET/SDH specification according to RFC
2615(1619)/1662 of the PPP Working Group of the Internet Engineering Task Force (IETF).
Processes bit-serial 2488.32 Mbit/s STS-48 (STM-16-16c) data streams with on-chip clock and data
recovery and clock synthesis.
•
•
Complies with Bellcore GR-253-CORE jitter tolerance, jitter transfer and intrinsic jitter criteria.
Provides termination for SONET Section, Line and Path overhead or SDH Regenerator Section,
Multiplexer Section and High Order Path overhead.
•
•
•
Provides UTOPIA Level 3 32-bit wide System Interface (clocked up to 104 MHz) with parity support
for ATM applications.
Provides SATURN POS-PHY Level 3ä 32-bit System Interface (clocked up to 104 MHz) for Packet
over SONET (POS), or ATM applications.
Supports line loopback from the line side receive stream to the transmit stream and diagnostic
loopback from the line side transmit stream to the line side receive stream interface.
•
•
•
Provides support for automatic protection switching via a 4-bit LVDS 777.76 MHz port.
Provides a standard 5 signal IEEE 1149.1 JTAG test port for boundary scan board test purposes.
Provides a generic 16-bit microprocessor bus interface for configuration, control, and status
monitoring.
•
Low power 1.8V CMOS core logic with 3.3V CMOS/TTL compatible digital inputs and digital outputs.
PECL inputs and outputs are 3.3V compatible.
•
•
Industrial temperature range (-40C to +85C).
416 pin UBGA package.
