11.3 Gbps Rate-Selectable Limiting Amplifier

11.3 Gbps Rate-Selectable Limiting Amplifier - ONET8501PB
 

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.

The ONET8501PB provides a gain of about 34 dB which ensures a fully differential output swing for input signals as low as 20 mVpp. The output amplitude can be adjusted to 350 mVpp, 650 mVpp, or 850 mVpp. To compensate for frequency-dependent loss of microstrips or striplines connected to the output of the device, programmable preemphasis 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 3-mm × 3-mm, 16-pin VQFN package, typically dissipates less than 170 mW and is characterized for operation from &3150;40°C to 100°C.
