Communication infrastructure: 400 G 16 QAM, 100 G DP-QPSK pluggable optical modules in CFP/CFP2 Broadband gain stage and pre-amplifiers Broadband test and measurement equipment GENERAL DESCRIPTION The HMC7810A is a differential input and differential output, output enables system designers to maintain constant output by broadband linear amplifier, capable of driving a differential adjusting the gain of the amplifier via the VCTL pin through an indium phosphate (InP) Mach-Zehnder (MZ) modulator for external automatic gain control (AGC) circuit. The IC provides data center interconnect fiber optics or silicon photonics, or module designers with scalable supplies for optimizing power driving a single-ended, electroabsorption modulated laser dissipation vs. required linearity. The IC is in a 2.9 mm (EML) modulator for short reach or metro applications. The 2.9 mm leadless chip carrier (LCC) package and requires an HMC7810A supports data rates up to 32.0 Gbps with a gain external bias tee. The differential input and differential are flatness of up to 20 GHz. The integrated peak detector at the externally ac-coupled. No power supply sequencing is required. Rev.
