SN65LVDT348: Output impedance?

Collin Wells

Part Number: SN65LVDT348

Hello,

Would you possible to provide the output impedance information for the SN65LVDT348 at a few output frequencies?  We are performing signal integrity and need the product output impedance information.

    Hey Collin,

    The output impedance of this receiver can be estimated based on the output current (IOL/ IOH) and the VOL/ VOH levels. Rout = (VCC- VOH) / IOH, or VOL/ IOL. If we use the values in Electrical Characteristics, we get Rout = 100ohms for when VOL = 0.4V and IOL = 4mA (assuming VCC = 3.3V). Please refer to the diagram below for more specific values that can be calculated:
