HMC7LC DRIVER, DC - GHz Device Operation These devices are susceptible to damage from Electrostatic Discharge. Proper precautions should be observed during handling, assembly and test. The input to this device should be AC-coupled. To provide the typical Vp-p output voltage swing, a 1.2Vp-p AC-coupled input voltage swing is required. Device Power Up Instructions 1. Ground the device 2. Set Vgg to -2V (no drain current) 3. Set Vctl to +1V (no drain current) 4. Set Vdd to +V (no drain current). Adjust Vgg for Idd = 14mA Vgg may be varied between -1V and V to provide the desired eye crossing point percentage (i.e. % crosspoint) and a limited cross point control capability. Vdd may be increased to +7V if required to achieve greater output voltage swing. Vctl may be adjusted between +2V and +V to vary the output voltage swing. Device Power Down Instructions 1. Reverse the sequence identified above in steps 1 through 4.
