SATURN USER NETWORK INTERFACE CELL DELINEATION BLOCK
1 FEATURES
• Quad cell delineation device operating up to a maximum rate of 52 Mbit/s.
• Provides a UTOPIA Level 2 compatible ATM-PHY Interface.
• Implements the Physical Layer Convergence Protocol (PLCP) for DS1
transmission systems according to the ATM Forum User Network Interface
Specification and ANSI TA-TSY-000773, TA-TSY-000772, and
E1transmission systems according to the ETSI 300-269 and ETSI 300-270.
• Uses the PMC-Sierra PM4341 T1XC, PM4344 TQUAD, PM6341 E1XC, and
PM6344 EQUAD T1 and E1 framer/line interface chips for DS1 and E1
applications.
• Provides programmable pseudo-random test pattern generation, detection,
and analysis features.
• Provides integral transmit and receive HDLC controllers with 128-byte FIFO
depths.
• Provides performance monitoring counters suitable for accumulation periods
of up to 1 second.
• Provides an 8-bit microprocessor interface for configuration, control and
status monitoring.
• Provides a standard 5 signal P1149.1 JTAG test port for boundary scan board
test purposes.
• Low power 3.3V CMOS technology with 5V tolerant inputs.
• Available in a high density 256-pin SBGA package (27mm x 27mm).
The receiver section:
• Provides PLCP frame synchronization, path overhead extraction, and cell
extraction for DS1 PLCP and E1 PLCP formatted streams.
• Provides a 50 MHz 8-bit wide or 16-bit wide Utopia FIFO buffer in the receive
path with parity support, and multi-PHY (Level 2) control signals.
