简介
The GX76476 is a low-power, high-performance, quad-channel linear driver chip. It is designed for 400G/600G optical integrated transmitter small form factor (SFF) modules for metro and long-haul applications.
The GX76476 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 60Ω differential interface with an open-collector type output stage, and linear output voltage of 4.0Vppd suitable for silicon photonics modulator and multi-level modulations.
特性
- Data rate up to 64Gbps per channel for 400G/600G DP-mQAM applications
- >65GHz bandwidth
- >10dB dynamic range of gain control
- 2.7W (typical) at linear 4.0Vppd
- AC-coupled 100Ω differential input/open-collector configuration at the 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 SPI digital interface integration
