Читать на веб-сайте:

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.

Key performance specifications
  • Electro-Absorption Modulator driver or optical receiver amplifier
  • Linear amplifier with 16 dB gain
  • 25 kHz to 35 GHz bandwidth
  • 2.7 Vamp eye amplitude
  • 9 ps rise time
