HMC748

Would you inform us what are threshold voltages(high and low) for single-end inputs(AP and BP)?

Are they Input High Voltage and Input Low Voltage in Electrical Specifications in the data sheet?

Are their value correct?

    Hi,

    +/-50mV difference is a safe operation spot for AP-BP or SP-SN. Below that, you might see some SNR degradation.

    Input voltage range is Vcc-0.1 to Vcc-0.5 (3.2 to 2.8 for Vcc=3.3) for AP and BP.

    You should not exceed Vcc - 2.0 V to Vcc + 0.5 range for input voltages.

    Best regards
