TMUX03155 STS-3/STM-1 (AU-4) Multiplexer/Demultiplexer
Features
I
Multiplexes three STS-1 signals into a SONET
STS-3 signal.
I
Multiplexes three AU-3 signals into an SDH STM-1
(AU-4) signal via a TUG-3 construction.
I
Demultiplexes three STS-1 signals from a SONET
STS-3 signal.
I
Demultiplexes three AU-3 signals from an SDH
STM-1 (AU-4) signal via a TUG-3 deconstruction.
I
High-speed microprocessor interface configurable
to operate with most commercial microprocessors.
I
Detects STS-3/STM-1 (AU-4) loss-of-signal (LOS)
conditions.
I
Detects STS-3/STM-1 (AU-4) out-of-frame and
loss-of-frame (OOF/LOF) conditions.
I
Provides an 8-bit bus interface at the STS-1/AU-3
rate.
I
Provides a bit serial, nibble-wide, or byte-wide
interface at STS-3/STM-1 (AU-4) rate.
I
Provides STS-3/STM-1 (AU-4) selectable scram-
bler/descrambler functions and B1/B2/B3 genera-
tion/detection.
I
Accepts bit rate, nibble rate, or byte rate high-
speed clocks (155.52 MHz, 38.88 MHz, or
19.44 MHz, respectively).
I
STS-3/STM-1 (AU-4) internal clock and data
recovery. Meets type B jitter tolerance of ITU-T
G.958. Accommodates 0.5 UI jitter up to 20 MHz.
155.52 MHz input reference clock for on-chip PLL.
Has on-chip PLL for clock synthesis, requiring only
one external resistor. No output clock drift in
absence of data transitions once lock is acquired.
I
STS-1 termination mode.
I
–40 °C to +85 °C temperature range.
I
208-pin, shrink quad flat pack (SQFP) package.
I
Complies with GR-253-CORE (12/95), G.707
(3/96), G.783(1/94).
Applications
I
SONET/SDH line termination equipment.
I
SDH path origination and termination equipment.
I
SONET/SDH add/drop multiplexers.
I
SONET/SDH cross connects.
I
SONET/SDH test equipment.
Description
The TMUX03155 STS-3/STM-1 (AU-4) multiplexer
device provides three modes of operation: STS-3,
STM-1 (AU-4), and STS-1
modes. In STS-3 mode,
the TMUX03155 device provides all of the functions
necessary to multiplex and demultiplex up to three
STS-1 signals to/from a SONET STS-3 signal. In
AU-4 mode, the TMUX03155 provides the functional-
ity to multiplex and demultiplex up to three AU-3 sig-
nals to/from an STM-1 (AU-4) signal. In STS-1 mode,
the high-speed side of the TMUX03155 operates at
51.84 MHz and can be used for STS-1 termination
and for accessing transport overhead in the SONET
frame.
On the STS-3/STM-1 (AU-4) side, the device
can be configured for either a 1-bit serial data inter-
face, a 4-bit parallel (nibble-wide) data interface, or
an 8-bit parallel (byte-wide) data interface. This
allows the device to drive an OC3 optical signal
directly or to allow for modular growth in terminal or
add/drop applications. On the STS-1/AU-3 side, the
TMUX03155 device provides a bus mode that can
communicate with up to three STS-1/AU-3 devices at
19.44 Mbits/s. The TMUX03155 is designed to inter-
face with the Agere Systems Inc. TMPR28051
device, or equivalent, providing complete mapping/
unmapping from/to an STS-3/STM-1 (AU-4) signal
for up to 84 DS1 or 63 E1 signals.
