CM154 1-1 XC - OVERVIEW
OVERVIEW
SECTION 1
OVERVIEW
INTRODUCTION
The XC chassis is a single sided printed circuit board (PCB) very similar to the CA Chassis. During the manufacturing
process, the microprocessor will be programmed for any added features. Additional plug in boards with Jack Packs will
be added to the chassis to accommodate the different features: Stereo, Mono, Video/Audio in, etc.
The ICX2200 integrated circuit (IC) handles all of the audio/video, sync, and drive processing. The IC6000 is the main
microprocessor and the IC6001 is the EEROM memory. The keyboard and IR detector are tied directly to the IC6000. The
IC2100 handles the vertical sweep. At power on, voltages for the vertical and video output circuit are derived from this
sweep circuit.
Feature and component information is listed below for each of the XC models.
