SATURN USER NETWORK INTERFACE (155-QUAD)

1 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.
