Description
The XMT5370-622 is a high
performance uncooled optical
laser transmitter for CCITT SDH
and ANSI SONET applications. It
is designed with an ECL/PECL
logic interface for 622 MBd
transmission.
The transmitter incorporates
several features which simplify
system design. The
XMT5370-622 may be operated
with either +5 V or –5 V power
supplies. Its standard 10 KH ECL
data interface enables direct
interface with PECL or ECL logic.
The compact transmitter module
contains a pigtailed laser, data
interface, bias and modulation
control circuitry. Thus, no
external components or adjust-
ments are necessary. Finally, a
laser disable input is provided to
shut down the laser for standby
or test purposes.
The XMT5370-622 includes
analog outputs which are
proportional to laser current and
optical power. These may be used
with external circuitry to detect
end-of-life, or over temperature
conditions.
The transmitter is packaged in a
20 pin 0.4" pitch DIP. Contact
your local representative for
more details.

Functional Description
The ECL input allows operation
from many logic families and
both single-ended or differential
signals. For single-ended
operation both DATA and DATA
are internally tied to a VBB. The
unused input then requires no
connection or biasing.
The disable function disables the
laser bias and modulator. The
switching threshold is VCC –3.2 V.
If this input is not connected the
module is enabled. This input
may be connected to a CMOS HI
or tied to VCC to disable.
The module provides the
necessary bias and modulation
control to maintain the extinction
ratio at better than 8.2 dB and
the waveform is compliant with
SONET/SDH Eyemask standard
G.957.
The laser bias control loop
compensates for temperature
induced variations in laser
performance. The bias current
monitor indicates the amount of
dc current supplied to the laser.
(This is approximately the laser
threshold current).
The rear facet monitor is a signal
proportional to the laser output
power. This can be used as part
of a HI/LO light alarm.
In the absence of data the laser
will emit a mean optical power
within the specified limits. The
extinction ratio and duty cycle
distortion are specified assuring a
50% duty cycle at the correct
data rate.
