SATURN USER NETWORK INTERFACE (622-MAX)

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

• Detects out of cell Delineation (OCD) and loss of cell delineation (LCD) alarms.

• Counts number of received cells, idle cells, errored cells and dropped cells.

• Provides a UTOPIA Level 2 compliant 16-bit wide datapath interface (clocked up

to 50 MHz) with parity support to read extracted cells from an internal four-cell

FIFO buffer.

• Provides a UTOPIA Level 3 compatible 8-bit wide datapath interface (clocked up

to 100 MHz) with parity support to read extracted cells from an internal four-cell

FIFO buffer.

1.4

The SONET Transmitter

• Synthesizes the 622.08 MHz transmit clock from a 77.76 MHz reference.

• Provides a differential PECL bit-serial interface at 622.08 Mbit/s.

• Inserts a register programmable path signal label (C2).

• Generates the transmit payload pointer (H1, H2) and inserts the path overhead.

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

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

• Optionally inserts externally generated data communication channels (D1-D3,

D4-D12) via a 192 kbit/s (D1-D3) serial stream and a 576 kbit/s (D4-D12) serial

stream.

• Scrambles the transmitted STS-12c/STM-4-4c or STS-3c/STM-1 stream and

inserts the framing bytes (A1, A2).

• Optionally inserts register programmable APS bytes.

• Provides a byte-serial transmit path data stream allowing two devices to

implement 1+1 APS.

• Inserts path BIP-8 codes (B3), path remote error indications (REI-P), line BIP-96

codes (B2), line remote error indications (REI-L), and section BIP-8 codes (B1) to

allow performance monitoring at the far end.

• Allows forced insertion of all-zeros data (after scrambling) and the corruption of

the section, line, or path BIP-8 codes for diagnostic purposes.
