LXT6234
E-Rate Multiplexer
Datasheet
The LXT6234 E-Rate Multiplexer is a single-chip solution for multiplexing four tributary
channels into a single high speed data stream and for demultiplexing a high speed data stream
back to four tributary channels. All of the necessary circuitry is integrated into the LXT6234 E-
Rate Multiplexer; there is no need for an external framing device.
The LXT6234 E-Rate Multiplexer conforms to both the (ITU) G.742 and (ITU) G.751
multiplexing formats defined by the International Telecommunications Union (ITU; formerly
known as CCITT): G.742 recommendation for multiplexing four E1 channels into an E2 frame;
and the G.751 recommendation for multiplexing four E2 channels into an E3 frame.
The LXT6234 E-Rate Multiplexer also encodes and decodes HDB3 zero suppression line coding
used on E1, E2, and E3 signals. The coder and decoder input/output pins are externally
accessible, allowing either HDB3 or NRZ (non-return-to-zero) I/O to the multiplexer. The
LXT6234 E-Rate Multiplexer can also serve as a five channel HDB3 coder and decoder.

Product Features
n
Performs four-E1 to one-E2, or four-E2 to
one-E3 multiplexing. Five ICs will
implement a sixteen-E1 to one-E3
multiplexer.
n
Fully compliant with the G.742 and G.751
ITU recommendations. Fully compliant
with G.703 when used with LXT305/332
Line Interface.
n
A robust frame-acquisition and frame-
holding algorithm minimizes frame
slippage, acquires and holds frame below
10
-2
bit error rate.
n
Four auxiliary low speed data or flag
channels are available via the Stuffing Bits
on each tributary channel.
n
Access to the Alarm bit and the National
bit. These can be used as recommended by
ITU or for proprietary use.
n
Five independent HDB3 CODECs allow
multiplexer I/O in either HDB3 or NRZ
formats. The LXT6234 can also function as
a stand alone five-channel HDB3
transcoder.
