Texas Instruments ONET2804TLP
The ONET2804TLP device is a high-gain, limiting transimpedance amplifier (TIA) for parallel optical interconnects with data rates up to 28 Gbps. The device is used in conjunction with a 750-μm pitch photodiode array to convert an optical signal into a differential output voltage. The device can be used with pin control or a two-wire serial interface to allow control of the output amplitude, gain, bandwidth, and input threshold.| Part No. | ONET2804TLP |

DESCRIPTION
An internal circuit provides the photodiode reverse bias voltage and senses the average photocurrent supplied to each photodiode. The ONET2804TLP provides 17.5-GHz bandwidth, a gain of 7.5 kΩ, an input-referred noise of 2 µArms, and a received signal strength indicator (RSSI) for each channel.
