PCD4440T General Description

The PCD4440T is a silicon gate CMOS integrated circuit intended to be used in cordless telephony, radio, and line telecommunications products utilizing a microcontroller for the control functions. The purpose of the device is to prevent unauthorized 'listening-in' on conversations. A major application is protection of the vulnerable radio link between a CT0 type cordless handset and its base unit. Analog scrambling/descrambling is based on the split frequency method realized in a sophisticated switched-capacitor technology. The PCD4440T is compatible with most microcontrollers and communicates via a two line bidirectional I2C-bus.

PCD4440T Features

· Scrambler or descrambler function
· Scrambling in frequency domain
· Selectable split frequency (up to 10 selections per second)
· Telephony-band filtering included
· No increase in bandwidth
· No external components required
· Small signal delay
· Insensitive to distortion and group delay of transmission channel
· Control via serial I2C-bus
· Low transfer loss of speech
· Mute option
· Transparent mode
· High signal input impedance
· Low signal output impedance
· Low power consumption.

PCD4440T Typical Application

· Cordless telephones
· Security telephones
· Portable phones
· Private Mobile Radio (PMR).
