SATURN USER NETWORK INTERFACE PLUS

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

FEATURES

• Monolithic Saturn User Network Interface that implements the ATM physical

layer for Broadband ISDN according to ANSI, ITU, and ATM Forum

specifications.

• Processes duplex 155.52 Mbit/s STS-3c/STM-1 or 51.84 Mbit/s STS-1 data

streams with on-chip clock and data recovery and clock synthesis.

• Provides Saturn Compliant Interface - PHYsical layer (SCI-PHY™) FIFO

buffers in both transmit and receive paths with parity support.

• Provides a generic 8-bit microprocessor bus interface for configuration,

control, and status monitoring.

• Provides a standard 5 signal IEEE 1149.1 JTAG test port for boundary scan

board test purposes.

• Low power, +5 Volt, CMOS technology.

• 208 pin high performance plastic quad flat pack (PQFP) 28 mm x 28 mm

package.

• Industrial temperature range operation (-40°C to +85°C).

The receiver section:

• Provides a serial interface at 155.52 or 51.84 Mbit/s.

• Recovers the clock and data.

• Frames to and descrambles the recovered stream.

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

readable registers and detects APS byte failure.

• Captures the synchronization status (S1) byte in a readable register.

• Interprets the received payload pointer (H1, H2) and extracts the STS-3c/1

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