概要
説明
The GX79472 is a low-power, high-performance, quad-channel linear driver chip that is designed for 800G and beyond optical integrated transmitter small form factor (SFF) modules for metro and long-haul applications.
The GX79472 integrates the quad lanes of the driver with SPI circuitry for DC controls on a single die. Each channel of the driver has a 100Ω differential AC-coupled input and a single-ended output with a back-terminated output stage. The output stage allows for an external AC-coupled interface with optical modulators having a wide characteristic impedance range from 30Ω to 50Ω. The linear output voltage of 2.0Vpps is suitable for the lithium niobate (LiNbO3) optical modulators with multi-level modulations.
特長
- Data rate up to 96Gbaud per channel for 800G and beyond DP-mQAM applications
- >70GHz E/O bandwidth
- >10dB dynamic range of gain control
- 3.8W (typical) at linear 2.0Vpps
- AC-coupled 100Ω differential input/30Ω - 50Ω single-ended output
- Ultra-low inter-channel crosstalk
- Peaking adjustment functionality
- Analog control for gain and output voltage setting, and analog monitor for peak detector and gain control monitor
- Optical Internetworking Forum (OIF)-compliant serial peripheral interface (SPI) digital interface integration
