Features, Applications

The MC13111 integrates several of the functions required for a cordless telephone into a single integrated circuit. This significantly reduces component count, board space requirements, external adjustments, and lowers overall costs. It is designed for use in both the handset and the base. Dual Conversion FM Receiver Complete Dual Conversion Receiver Antenna In to Audio Out 80 MHz Maximum Carrier Frequency RSSI Output Carrier Detect Output with Programmable Threshold Comparator for Data Recovery Operates with Either a Quad Coil or Ceramic Discriminator Compander Expandor Includes Mute, Digital Volume Control, Speaker Driver, 3.5 kHz Low Pass Filter, and Programmable Gain Block Compressor Includes Mute, 3.5 kHz Low Pass Filter, Limiter, and Programmable Gain Block Dual Universal Programmable PLL Supports New 25 Channel U.S. Standard with No External Switches Universal Design for Domestic and Foreign CT1 Standards Digitally Controlled Via a Serial Interface Port Receive Side Includes 1st LO VCO, Phase Detector, and 14Bit Programmable Counter and 2nd LO with 12Bit Counter Transmit Section Contains Phase Detector and 14Bit Counter MPU Clock Outputs Eliminates Need for MPU Crystal Supply Voltage Monitor Provides Two Levels of Monitoring with Separate Outputs Separate, Adjustable Trip Points Programmable Corner Frequency Selection
