Receiver Characteristics

The uPSD321x Devices has a differential input re-

ceiver which is able to accept the USB data signal.

The receiver features an input sensitivity of at least

200mV when both differential data inputs are in

the range of at least 0.8V to 2.5V with respect to

its local ground reference. This is the common

mode range, as shown in Figure 41. The receiver

tolerates static input voltages between -0.5V to

3.8V with respect to its local ground reference

without damage. In addition to the differential re-

ceiver, there is a single-ended receiver for each of

the two data lines. The single-ended receivers

have a switching threshold between 0.8V and 2.0V

(TTL inputs).
