1. General Description
eKM8003 is designed as a 3-D 3-Keys or 5-Keys
PS/2 optical mouse controller. It must apply with
Agilent sensor ADNS-2051, ADNS-2610, ADNS-
2620 or the same compatible series sensor.
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.
1.
Mechanical encoder (Z/2).
2.
Photo couples input for Z/2.
3.
