Single chip ATM and Packet over SONET/SDH 8-channel Physical Layer Device operating
at 155.52 Mbit/s.
Implements the ATM Forum User Network Interface Specification and the ATM physical
layer for Broadband ISDN according to ITU Recommendation I.432.
Implements the Point-to-Point Protocol (PPP) over SONET/SDH specification according to
RFC 2615 and RFC 1662.
Processes eight 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 (2000 Issue) jitter tolerance, jitter transfer (1995
Issue) 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 UTOPIA Level 3 compatible 32-bit wide System Interface (clocked up to 104
MHz) with parity support for ATM applications.
Provides SATURN POS-PHY Level 3ä 32-bit System Interface (clocked up to 104 MHz)
for Packet over SONET/SDH (POS) and ATM applications.
Provides support functions for 1+1 APS and 1:N operation.
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 volt CMOS with 5-volt TTL compatible digital inputs and outputs.
PECL inputs and outputs are 3.3 volt and 5 volt compatible.
Industrial temperature range (-40°C to +85°C).
520 pin Super BGA package.
Provides eight serial interfaces at 155.52 Mbit/s with clock and data recovery.
Frames to and de-scrambles the received STS-3c/STM-1 streams.
Interprets the received payload pointers (H1, H2) and extracts the STS-3c/STM-1
synchronous payload envelopes and path overheads.
Extracts the data communication channels (D1-D3, D4-D12) and serializes them at
192 kbit/s (D1-D3) and 576 kbit/s (D4-D12) for optional external processing.
