S/UNI®-16x155
16-Channel OC-3c ATM and POS Physical Layer Device
FEATURES
• Single chip 16-channel ATM and POS
User Network Interface operating at
155 Mbit/s.
• Implements the ATM Forum User
Network Interface Specification and
the ATM physical layer for Broadband
ISDN according to CCITT
Recommendation I.432.
• Implements the Point-to-Point Protocol
(PPP) over SONET/SDH specification
according to RFC 2615(1619)/1662 of
the PPP Working Group of the Internet
Engineering Task Force (IETF).
• Processes sixteen bit-serial 155 Mbit/s
STS-3c (STM-1) data streams with on-
chip clock and data recovery and clock
synthesis.
• Complies with Bellcore GR-253-CORE
jitter tolerance, jitter transfer and
intrinsic jitter criteria.
• Each channel provides termination for
SONET Section, Line and Path
overhead or SDH Regenerator
Section, Multiplexer Section and High
TDCLK[15:0]
TDCC[15:0]

Provides UTOPIA Level 3 32-bit wide
System Interface (clocked up to
104 MHz) with parity support for ATM
applications.
Provides SATURN
®
POS-PHY
Level 3™ 32-bit System Interface
(clocked up to 104 MHz) for Packet
over SONET (POS), or ATM
applications.
Supports line loopback from the line
side receive stream to the transmit
stream and diagnostic loopback from
the line side transmit stream to the line
side receive stream interface.
Provides support for automatic
protection switching including a bi-
directional 4-bit PECL 622 MHz port
for external APS with mate device.
Built-in APS cross-connect for internal
and external 1+1 and 1:n protection
switching.
Provides a standard five signal IEEE
1149.1 JTAG test port for boundary
scan board test purposes.
• Provides a generic 16-bit
microprocessor bus interface for
configuration, control, and status
monitoring.
