- 32 GBd linear differential driver for telecom and datacom applications
Technical Background
HHI provides open-collector SiGe linear driver IC for InP Mach-Zehnder modulator. Its differential output is suitable to drive InP Mach-Zehnder modulator having 2x 25 Ω. It integrates output peak-level detectors and consumes 270 mW per channel. It enables the electro-optical module to consume the lowest power.
