Receiver Characteristics
The
μ
PSD323XDevices hasa differential input re-
ceiver which is able to accept the USB data signal.
The receiverfeatures aninput 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 isa single-ended receiver for each of
the two data lines. The single-ended receivers
have a switching thresholdbetween 0.8V and 2.0V
(TTL inputs).
