2 Integrating the CM52 Wireless CPU

2.1

Overview

The CM52 is a dual band, dual mode CDMA transceiver Wireless CPU
band for CDMA and AMPS and in the 1900 MHz band for CDMA. It is designed for consumer and
OEM industrial voice and data applications.
The CM52 Wireless CPU
provide wireless communication capability for the product. The target chassis could be in a wide
variety of forms such as a residential electric meter, a point of sale terminal, an alarm panel, or an
automobile console. All initial configuration, mode control, and operational commands are issued
to the Wireless CPU
CPU circuitry has been designed to meet the environmental requirements of a large range of
®
commercial and industrial users.

Mechanical Description

The CM52 has no mechanical elements other than the main PCB assembly. All critical electronic
components are shielded using six cans to prevent internal and external electromagnetic
interference from degrading the Wireless CPU performance and to prevent the Wireless CPU
interfering with other nearby devices. The Wireless CPU
connector and secured with four screws.
The antenna interface is provided via a board mounted RF connector at the opposite end of the
board from the system connector. See Section 2.8 for more information on antenna connector
options.
