Details
GENERAL DESCRIPTIONThe 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).
