概要
説明
The RG8G71474 is a low-power, high-performance, 128Gbaud quad-channel linear driver chip designed for 800Gbps and beyond optical integrated transmitter small form factor (SFF) modules for metro and long-haul applications.
The RG8G71474 integrates analog control and digital (through an SPI interface) control circuitry for precise, independent driving level control and monitoring. Each driver channel has a 100Ω differential AC-coupled input and 60Ω differential interface with an open-collector type output stage and is suitable for InP-based and silicon photonics-based Mach-Zehnder modulators.
特長
- >85GHz 3dB bandwidth with >75GHz peaking frequency
- 15dB (typical) of peaking to compensate for package and modulator losses
- >10dB dynamic range of gain control
- 3.0W (typical) power consumption for 2.5Vppd output voltage swing
- AC-coupled 100Ω differential input
- Open-collector configuration output stage that can drive DC-coupled 60Ω differential
- Ultra-low inter-channel crosstalk
- Precise analog and digital monitoring and control of gain and output voltage swing
- <1MHz low-frequency cutoff
- Optical Internetworking Forum (OIF)-compliant serial peripheral interface (SPI) for programmability
