5-4. Timing and state diagrams
5-4-1. Quadrature Output Waveform
The output signals are two channels quadrature (X and Y), which emulates encoder
phototransistors. Sensor IC generates X and Y relative displacement values that are converted
into two channel quadrature signals. The two channel quadrature outputs are 3.5V signals. The X
and Y counts are used to generate the X1, X2 and Y1, Y2 quadrature signals. The quadrature
signals can change at a maximum rate of 25 KHz. The following diagrams show the timing for
positive X motion, to the right direction.

5-4-2. PD Pin Timing
z Pulse width to initiate the power down mode, tPDW (Power Down Pulse Width) minimum time
is 720μs.
z When the mouse is fully active again, tPUPD (Power Up from PD) maximum time is 300ms.

Un datasheet est un document fourni par le constructeur du composant, où figurent toutes les données techniques sur le produit: puissance dissipée, courant maximal, tension de seuil, tension de claquage, température de stockage, etc. Ils sont en général fournis gratuitement, et se présentent très régulièrement sous la forme d'un document pdf.
