Circuit Operation (Handset)

4.7.1.

Outline

Handset consists of the following ICs as shown in

Block Diagram (Handset)

(P.18).

• DECT BBIC (

ase

and IC): IC1

- All data signals (forming/analyzing ACK or CMD signal)
- All interfaces (ex: Key, Detector Circuit, Charge, EEPROM, LCD)

• EEPROM: IC3

- Setting data is stored. (e.g. ID, user setting)

4.7.2.

Power Supply Circuit/Reset Circuit

Circuit Operation:

When power on the Handset, the voltage is as follows;
BATTERY(2.2 V ~ 2.6 V: BATT+)

→

BBC1 (IC1) 10 pin

The Reset signal generates IC1 (54 pin) and 1.8 V.
