产品详情

The HMC7810A is a differential input and differential output, broadband linear amplifier, capable of driving a differential indium phosphate (InP) Mach-Zehnder (MZ) modulator for data center interconnect fiber optics or silicon photonics, or driving a single-ended, electroabsorption modulated laser (EML) modulator for short reach or metro applications. The HMC7810A supports data rates up to 32.0 Gbps with a gain flatness of up to 20 GHz. The integrated peak detector at the output enables system designers to maintain constant output by adjusting the gain of the amplifier via the VCTL pin through an external automatic gain control (AGC) circuit. The IC provides module designers with scalable supplies for optimizing power dissipation vs. required linearity. The IC is in a 2.9 mm × 2.9 mm leadless chip carrier (LCC) package and requires an external bias tee. The differential input and differential are externally ac-coupled. No power supply sequencing is required.

Applications

Communication Infrastructure: 400G 16QAM, 100G DP-QPSK pluggable optical modules in CFP/CFP2

EV1HMC7810ALC3 is a populated, Rogers 4350B based evaluation board. For normal operation, it requires two external supply voltages V_DD : 3.3V/150mA at the supply pin V_DD and V_{DD_EXTP}/V_{DD_EXTN}. To adjust the gain of HMC7810A V_CTL test point can be used. When VCTL is −1.5 V, the gain is maximum, and when VCTL is 0 V, the gain is minimum. In addition the outputs VDET and VREF of the internal peak detector can be monitored from the test point which are labeled VDET and VREF. To implement an external automatic gain control, use an analog attenuator and the features of the peak detector.
