RIPTION The Pixi Point TM Z mouse encoder is a cost-effective, highfunctionality IC designed to interface the CTS 106, 108 and 109 sensors to the PS/2 port. Ideal for laptop/palmtop use, the low power Pixi Point TM Z offers an advanced algorithm for enhanced motion control. The IC also enables click, double-click, Mouse Wheel action and slow drag without the need for special drivers. The IC provides an extra port for hot-plug connection of an external pointing device, including those with built-in Mousewheel. Both the embedded sensor and the external device can be operated concurrently. The Pixi Point TM Z utilizes a special signal conditioning circuit (US and International patent pending) which enables a low cost, simple and real estate-saving implementation. Just a few low tolerance external ponents are needed. The IC implements typically consumes less than 3m A, making it suitable for use in battery-operated systems. PS/2 munication is bidirectional at 10 kbps. The IC, a CMOS device operating at 4 MHz, is patible with both the IBM and Microsoft two-button and the Logitech three-button mouse protocols. It implements all mands from and to the system, as defined in the IBM PS/2 Mouse munication Protocol. Custom versions are also available to suit a range of applications. 32 1 Features - Accurate cursor control via Semtech’s Advanced Motion Control algorithm - Click (Select), Double-Click (Execute), Mouse Wheel and slow drag are implemented in the IC - no special driver support required - Enables hot-plug connections of an external pointing device, including those with Mouse Wheel - Offers concurrent operation of force stick and external pointing device - Provides ideal interface for CTS Series 106, 108 and 109 sensors - Low power consumption of typically less than 3m A makes it ideal for battery-operated systems - 3-5V operation in extended temperature range APPLICATIONS - Notebooks/laptops - Handhelds PIN ASSIGNMENTS - Keyboards - Instrumentation - Can utilize standard...
