2 Application and Features
Application for the PS/2 optical mouse which supports 3-Dimensions with 3-Keys
or 5-Keys.
eKM8003 supports Agilent sensor IC (ADNS-2051,
ADNS-2610 and ADNS-2620). It also supports 400/800
CPI via CPIS selection pin for ADNS-2051 only.
eKM8003 supports 3 types of Z direction input which Z1and Z2
stable state must be the same voltage level. Where Z1 and Z2 with
internal pull down resisters 100KOhm.
1. Mechanical encoder (Z/2).
2. Photo couples input for Z/2.
3. Photo couples input for Z/4.
