Chapter 3 Functional Description

3.1 Introduction

This chapter gives an overview of the CC175 module and a detailed description of the functional sections. The block diagram of the module is given in Appendix A.

Two types of symbols are used in the schematic diagrams. One represents hierarchical components and is referenced with a component number (CMPxxx). The detailed circuit diagram of these components are shown on a separate sheet. The other type of symbol represents the actual physical components and is referenced with a corresponding letter (i.e. U for ICs, P for connectors, R for resistors, etc.). Physical components have pin numbers assigned to their symbol pins, while hierarchical components have no pin numbers.

Signal names ending with a tilde (~) or an asterisk (*) are active low.
