SATURN USER NETWORK INTERFACE 155 (STAR)

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

• 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.

• Captures and debounces the synchronization status (S1) byte in a

readable register.

• Filters and captures the automatic protection switch channel (K1, K2)

bytes in readable registers and detects APS byte failure.

• Counts received section BIP-8 (B1) errors, received line BIP-24 (B2)

errors, line far end block errors (FEBE), and received path BIP-8 (B3)

errors and path far end block errors (FEBE).

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

line alarm indication signal (LAIS), line remote defect indication (LRDI),

loss of pointer (LOP), path alarm indication signal (PAIS), path remote

defect indication (PRDI) and path extended remote defect indicator

(PERDI).

• Extracts the section and line data communication channels (D1-D3

and D4-12) as selected in internal register banks and serializes them

at 192 Kbit/s (D1-D3) and 576 Kbit/s (D4-D12) for optional external

processing.

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

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

• Interprets the received payload pointer (H1, H2) and extracts the STS-

3c (STM-1) synchronous payload envelope and path overhead.

• Provides a divide by 8 recovered clock (19.44 MHz).

• Provides a 8KHz receive frame pulse.
