DETAILED DESCRIPTION

BLOCK DIAGRAM

The ONET2511TA is a high performance 2.5 Gbps transimpedance amplifier that can be segmented into the

signal path, filter, and offset cancellation block.

The signal path consists of a transimpedance amplifier stage, a voltage amplifier, and an output buffer.

The filter circuit provides a filtered VCC for the photodiode.

The offset correction circuit uses an internal low pass filter to cancel the DC on the input and it provides a signal

to monitor the received signal strength.

A simplified block diagram of the ONET2511TA is shown in Figure 1.
