This significantly reduces component count, board space requirements, and external adjustments. It is designed for use in both the handset and the base. • Dual Conversion FM Receiver – Complete Dual Conversion Receiver – Antenna Input to Audio Output 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 and Speaker Driver – Compressor Includes Mute, ALC and Limiter • Dual Universal Programmable PLL – Supports New 25 Channel U.S. Standard with No External Switches – Universal Design for Domestic and Foreign CT–1 Standards – Digitally Controlled Via a Serial Interface Port – Receive Side Includes 1st LO VCO, Phase Detector, and 14–Bit Programmable Counter and 2nd LO with 12–Bit Counter – Transmit Section Contains Phase Detector and 14–Bit Counter – MPU Clock Output Eliminates Need for MPU Crystal • Supply Voltage Monitor – Externally Adjustable Trip Point • 2.0 to 5.5 V Operation with One–Third the Power Consumption of Competing Devices • AN1575: Refer to Application Note for a List of “Worldwide Cordless Telephone Frequencies” (Chapter 8 Addendum of DL128 Data Book) UNIVERSAL CT–1 SUBSYSTEM INTEGRATED CIRCUIT 52 1 FB SUFFIX PLASTIC PACKAGE CASE 848B (QFP–52) 48 1 FTA SUFFIX PLASTIC PACKAGE CASE 932 (Thin QFP) ORDERING INFORMATION Device Tested Operating Temperature Range Package MC13109FB MC13109FTA QFP–52 TA = –20° to +85°C TQFP–48 Simplified Block Diagram Rx In 1st Mixer 2nd Mixer Limiting IF Amplifier Detector Carrier Detect Tx In Tx Out Tx VCO 1st LO PLL 2nd LO PLL Mute Compressor Tx Phase Detector RSSI Mute Expander µP Serial Interface Low Battery Detect This device contains 6,609 active transistors.

The FM receiver and 1st LO have been designed to work for all country channels, including 25 channel U.S., without the need for any external switching circuitry (see Figure 29). (Test Conditions: VCC = 2.6 V, TA = 25°C, fO = 46.61 MHz, fDEV = ± 3.0 kHz, fmod = 1.0 kHz.)

The voltage at the “Ref” input pin is compared to an internal 1.23 V Bandgap reference voltage. The “BD Out” pin is open collector and requires and external pull–up resistor to VCC.
