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