IN3250TA: 32 Gbaud Dual, Differential Input, Linear Transimpedance/Variable Gain Amplifier 

Model: IN3250TA

Package: BGA

Type: Transimpedance Amplifier

Application: 100G/200G Coherent Receiver 20-stage ICR

The IN3250TA is a dual-channel, differential linear transimpedance/variable gain amplifier (TIA/VGA) for 100G and 200G coherent detection receivers for long-haul and metro networks.

The IN3250TA offers two gain control modes: manual and automatic. In manual mode, the gain is controlled by an external control pin. In auto mode, the gain is automatically adjusted to provide a constant output voltage.

The IN3250TA has a bandwidth adjustable feature that allows the user to optimise the receiver frequency response for different photodiode and ADC/DSP combinations.

The IN3250TA is powered by a +3.3 V supply and is supplied as a bare die.
