PSPL5882 40 Gb/s Broadband Amplifier Datasheet

PSPL5882 Datasheet

The PSPL5882 is extremely broadband, covering over 6 decades from 25 kHz to 35 GHz. It also demonstrates a very clean time domain response, resulting in high quality 40 Gb/s eye diagrams. The PSPL5882 includes internal reverse voltage protection, power supply regulation, and sequencing circuitry, making it insensitive to power supply voltage variation and application sequence.
