PM5384 S/UNI®-1x155 Advance Single Channel OC-3c ATM and POS Physical Layer Device FEATURES • Single chip ATM and Packet over SONET/SDH Physical Layer Device operating at 155.52 Mbit/s. • Implements the ATM Forum User Network Interface (UNI) and the ATM physical layer for Broadband ISDN according to CCITT Recommendation I.432. • Implements Point-to-Point Protocol (PPP) over SONET/SDH according to RFC 2615. • Processes duplex bit-serial 155.52 Mbit/s STS-3c/STM-1 data streams with on-chip clock and data recovery and clock synthesis. • Complies with Bellcore GR-253-CORE (1995 Issue) jitter tolerance, jitter transfer and intrinsic jitter criteria. • Provides control circuitry required to comply with Bellcore GR-253-CORE WAN clocking requirements related to wander transfer, holdover and long term stability when using an external VCXO. • Provides a UTOPIA Level 2, 8-bit wide system interface (clocked up to 52 MHz) with parity support for ATM applications. • Provides a UTOPIA Level 2, 16-bit wide system interface (clocked up to 52 MHz) with parity support for ATM applications. • Provides a SATURN POS-PHY Level 2, 16-bit system interface (clocked up to 52 MHz) for Packet over SONET/SDH (POS) applications (similar to UTOPIA Level 2, but adapted for packet transfer). • Provides support functions for 1+1 APS operation. GENERAL • 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 2.5/3.3 V CMOS with 5 V TTL-compatible digital inputs/outputs (PECL inputs/outputs are 3.3 V and 5 V compatible). • Industrial temperature range (-40°C to +85°C). • 15 mm x15 mm 196 pin stPBGA package with 1 mm ball pitch. APPLICATIONS • • • • • • • Routers and Layer 3 Switches. 3G Wireless Base Station Controllers. DSLAM Uplinks. WAN and Edge ATM switches. LAN switches and hubs. Packet switches and hubs.
