Receiver Characteristics
The μPSD325X 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 45. 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).
