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
The ONET1151P provides a gain of about 33dB which ensures a fully differential output
swing for input signals as low as 20 mVp-p. The output amplitude can be
adjusted between 350 mVp-p and 850 mVp-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 × 3 mm 16-pin QFN package,
typically dissipates 132 mW with 550 mVp-p output and is characterized for
operation from −40°C to 100°C.
