NOV2124 PRODUCT BRIEF
NOV2124TM
Quad PORT ATM/POS 155 Mb/s PHYSICAL LAYER IC
1. GENERAL DESCRIPTION
The NOV2124 is an integrated circuit
that implements four-channel
ATM/Packet Over SONET/SDH
(POS) processing functions at 155.52
Mb/s. The part contains both the PMD
and the TC sublayers and has
UTOPIA Level 2 interface to the ATM
layer or optionally POS interface to
the link layer. The device also
includes dedicated serial ports for the
insertion and extraction of the DCC
overhead bytes.
The NOV2124 is fully compliant with
the SONET/SDH, B-ISDN ATM Forum
User Network Interface requirements
and standards, and compliant with
PPP protocol over SONET/SDH (RFC
1619/1662 of the IETF). The PMD
sublayer is based on Novanet
Semiconductor’s Hi-PHY
technology for high-speed data and
clock recovery. The UTOPIA Level
2/POS interfaces provide variable
modes of operation when interfacing
the ATM layer or link layer in order to
facilitate the connection of the
NOV2124 to different ATM layer or
Packet Over SONET/SDH link layer
devices.
The NOV2124 is targeted primarily for
use within ATM switches, routers and
WAN switches supporting Packet
Over SONET/SDH. The device is
manufactured using 0.35µ CMOS
technology and packaged in a 256 pin
PBGA package.
