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.
