iT3020
Description
The i T3020 is a highly linear low noise differential variable gain amplifier with a bandwidth of DC to 10 GHz. It is suitable for Automatic Gain Control (AGC) in high bandwidth applications such as a 10/12.5 Gb/s STM-64/OC-192 receiver front end. Offset correction and shutoff control are provided. Both AC and DC coupling are allowed at the input and output. High sensitivity allows the device to be used at the output of a transimpedance amplifier. 3-d B bandwidth: 10 GHz Differential gain: 29 d B Bias supply: -5 V, 156 m A, and +5 V, 74 m A Power consumption: 1150 m W Gain control: 30 d B CMRR: Better than 25 d B DC offset correction Low RMS jitter Low-cost JEDEC QFP-N (MO-220) package
