DESCRIPTION
The ONET1151L device is a 3.3-V laser driver
designed to directly modulate a laser at data rates
from 1 to 11.3 Gbps.
The device provides a 2-wire serial interface, which
allows digital control of the modulation and bias
currents, eliminating the need for external
components. Output waveform control, in the form of
cross-point adjustment, de-emphasis, and output
termination resistance are available to improve the
optical eye mask margin. An optional input equalizer
can be used for equalization of up to 150 mm (6 in.)
of microstrip or stripline transmission line on FR4-
printed circuit boards. The device contains internal
ADC and DACs to eliminate the need for special
purpose microcontrollers.
The ONET1151L device includes an integrated
automatic power control (APC) loop, which
compensates for variations in laser average power
over voltage and temperature and circuitry to support
laser safety and transceiver management systems.
The laser driver is characterized for operation from
–40°C ambient to +100°C temperatures and is
available in a small footprint 4-mm × 4-mm, 24-pin,
RoHS-compliant QFN package that is pin-compatible
to the ONET1101L device.
