Hi,
I used a HMC675LC3C as Analog Comparator High Speed.
The input INP receive an adjustable DC signal (0V to -0.75V) and the input INN a burst of negatives pulses . Pulses are 600ps width.
I would compare these 2 signals to obtain an output signal.
The Voltage Input Terminal VTx is put to the ground.
I used track mode (LE & LE_bar) floating.
Power are : Vcci 3.3V; Vcco : GND; Vee: -3V . The measured current are 10mA on Vee
The level on each output is to ground. I am not seing any signal with my scope (Scope input DC 50R)
I am so confused. Can TRACK mode be permantly floatting? Must VTx pin must be ground or put to a 2V level votage.
Best regards,
