HMC7810A Data Sheet

Rev. 0 | Page 10 of 14

THEORY OF OPERATION The HMC7810A is a broadband linear amplifier with a differential input and output. The device supports a maximum data rate of 32.0 Gbps with a typical bandwidth of 28 GHz. The HMC7810A is self biased and does not requires any bias sequencing or current adjustment circuitry. The device has two external supply voltages: VDD = 3.3 V supply at the supply pin and VDD_EXTP/VDD_EXTN. The VDD_EXTP/VDD_EXTN supply has two options: 2.5 V, which achieves better jitter performance, and 3.3 V, which achieves higher output voltage swings.

The HMC7810A includes an integrated analog that allows a gain adjustment of at least 6 dB. When VCTL is −1.5 V, the gain is maximum, and when VCTL is 0 V, the gain is minimum. The HMC7810A contains a peak detector that behaves linearly with respect to the output swing. The peak detector has two outputs, VDET and VREF. Use the difference of these voltages to read the output voltage swing. To implement an external automatic gain control, use an analog attenuator and the features of the peak detector.

Rev. 0 | Page 11 of 14

APPLICATIONS INFORMATION The HMC7810A can drive Mach-Zehnder modulators in differential or single-ended operation. To keep the output swing constant at a desired value, build an analog or digital gain control loop. To build a gain control loop, use the voltage difference of the VREF and VDET pins (VPEAK) as an input to an analog or digital gain control mechanism to drive the VCTL pin (see Figure 17). The HMC7810A requires an external bias from the output side; however, the modulator bias can be provided after a dc blocking capacitance.
