产品描述

The ONET8501PB 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 pre-emphasis, 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.

The ONET8501PB provides a gain of about 34dB which ensures a fully differential output swing for input signals as low as 20mVp-p. The output amplitude can be adjusted to 350mVpp, 650mVpp, or 850mVpp. To compensate for frequency dependent loss of microstrips or striplines connected to the output of the device, programmable pre-emphasis is included in the output stage. A settable loss of signal detection and output disable are also provided.

The device, available in RoHS compliant small footprint 3mm × 3mm 16-pin QFN package, typically dissipates less than 170 mW and is characterized for operation from -40°C to 100°C.
