General Description
The HMC1068 is a broadband distributed amplifier optimized for time-domain performance
with high bandwidth supporting data-rates up to 32Gbps. The output signal amplitude and
cross point are adjustable through the control pins and the integrated peak detector feature is
used for monitoring the output voltage signal levels during device's normal operation.
The HMC1068 is designed in GaAs MMIC PHEMT process and the device can support
wide supply (Vdd) voltage range from 3.3V to 7V with excellent performance, which gives
the system designers the flexibility to further optimize the power consumption of the device
by settings the supply voltage to its optimum value depending on the output voltage
requirements.
HMC1068 performance is optimized for operating as a pre-stage amplifier in a cascaded
configuration when HMC1069 is used as post-stage driver.
The HMC1068 comes in a small die size and need minimal number of external components
for decoupling only, which makes it well suited for driver integrated optical modulator chip-
and-wire module assemblies..
