SATURN USER NETWORK INTERFACE (622-MAX)

PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA INC., AND FOR ITS CUSTOMERS’ INTERNAL USE

• 304 pin Super BGA package.

1.2

The SONET Receiver

• Provides a serial interface at 622.08 Mbit/s with clock and data recovery.

• Frames to and de-scrambles the received STS-12c/STM-4-4c stream.

• Optionally frames to and de-scrambles a received STS-3c/STM-1 stream.

• Interprets the received payload pointer (H1, H2) and extracts the STS-12c/STM-

4-4c or STS-3c/STM-1 synchronous payload envelope and path overhead.

• Filters and captures the automatic protection switch channel (APS) bytes in

readable registers and detects APS byte failure.

• Captures and de-bounces the synchronization status (S1) nibble in a readable

• Detects signal degrade (SD) and signal fail (SF) threshold crossing alarms based

on received B2 errors.

• Extracts the 16-byte or 64-byte section trace (J0/Z0) sequence and the 16-byte

or 64-byte path trace (J1) sequence into internal register banks.

• Detects loss of signal (LOS), out of frame (OOF), loss of frame (LOF), line alarm

indication signal (AIS-L), line remote defect indication (RDI-L), loss of pointer

(LOP), path alarm indication signal (AIS-P), path remote defect indication (RDI-

P), path extended remote defect indicator (extended RDI-P).

• Counts received section BIP-8 (B1) errors, received line BIP-96 (B2) errors, line

remote error indicates (REI-L), received path BIP-8 (B3) errors and path remote

error indications (REI-P) for performance monitoring purposes.

1.3

The Receive ATM Processor

• Extracts ATM cells from the received STS-12c/STM-4-4c or STS-3c/STM-1

payload using ATM cell delineation.

• Provides ATM cell payload de-scrambling.

• Performs header check sequence (HCS) error detection and correction, and

idle/unassigned cell filtering.
