DESCRIPTION
The ONET1151P is a high-speed, 3.3-V limiting amplifier for multiple fiber optic and copper cable applications
with data rates up to 11.3 Gbps.
The device provides a two-wire serial interface which allows digital control of the output amplitude, output pre-
emphasis, input threshold voltage (slice level) and the loss of signal assert level.
The ONET1151P provides a gain of about 33dB which ensures a fully differential output swing for input signals
as low as 20 mV_p-p. The output amplitude can be adjusted between 350 mV_p-p and 850 mV_p-p. To compensate for
frequency dependent loss of microstrips or striplines connected to the output of the device, programmable de-
emphasis is included in the output stage. A settable loss of signal (LOS) detection with programmable output
masking time and output disable are also provided.
The part, available in RoHS compliant small footprint 3 mm x 3 mm 16-pin QFN package, typically dissipates 132
mW with 550 mV_p-p output and is characterized for operation from −40°C to 100°C.
