描述
The RG8G72475 is a 32Gbaud low-power quad-channel limiting driver amplifier that is designed for 100Gbps DP-QPSK coherent pluggable module applications.
The RG8G72475 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 100Ω differential interface with an open-collector type output stage. The driver is designed with industrial temperature definition and provides the limiting output voltage of 2.7Vppd, which is suitable for driving InP-based and silicon photonics-based modulators.
The RG8G72475 is delivered as a die formed with solder bumps for the flip-chip assembly.
