3 Description
The ONET8501PB device is a high-speed, 3.3-V
limiting amplifier for multiple fiber optic and copper
cable applications with data rates from 2 Gbps up to
11.3 Gbps.
The device provides a two-wire serial interface which
allows digital control of the bandwidth, output
amplitude, output preemphasis, input threshold
voltage (slice level), and the loss of signal assert
level. Predetermined settings for bandwidth and LOS
assert levels can also be selected with external rate
selection pins.
