SATURN USER NETWORK INTERFACE (155-QUAD)

 

 

 

1 FEATURES

1.1General

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.

1.2The 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.
