3 Description
The ONET1130EP is an integrated modulator driver
and limiting amplifier designed to operate from 1
Gbps to 11.7 Gbps. Optical and electrical loopback
are included and a two-wire serial interface allows
digital control of the features.
The transmit path consists of an adjustable input
equalizer for equalization of up to 300 mm
(12 inches) of microstrip or stripline transmission line
of FR4 printed circuit boards, and an output
modulator driver. Output waveform control, in the
form of cross-point adjustment and de-emphasis are
available to improve the optical eye mask margin.
Bias current for the laser is provided and an
integrated automatic power control (APC) loop to
compensate for variations in average optical power
over voltage, temperature and time is included.
The receive path consists of a limiting amplifier with
programmable equalization and threshold adjustment,
and output de-emphasis to compensate for frequency
dependent loss of connectors, microstrips or striplines
connected to the output of the device, The receiver
output amplitude and loss of signal assert level can
be adjusted.
