1 / 43 page MC33411A/B 900 MHz ANALOG CORDLESS PHONE BASEBAND WITH COMPANDER FTA SUFFIX PLASTIC PACKAGE CASE 932 (LQFP–48) Device Operating Temperature Package ORDERING INFORMATION MC33411AFTA TA = –20 to 70°C LQFP–48 SEMICONDUCTOR TECHNICAL DATA Order this document by MC33411A/D MC33411BFTA 1 48 1 MOTOROLA RF/IF DEVICE DATA 900 MHz Analog Cordless Phone Baseband with Compander The MC33411 900 MHz Analog Cordless Phone Baseband system is designed to fit the requirements of a 900 MHz analog cordless telephone system. Included are three PLLs (Phase–Locked Loops). Two are intended for use with external VCOs and 64/65 or 128/129 dual modulus prescalers, and can control the transmit and receive (LO1) frequencies for 900 MHz communication. The third PLL is configured as the 2nd local oscillator (LO2), and is functional to 80 MHz. Also included are muting, audio gain adjust (internal and external), low battery/carrier detect, and a wide range for the PLL reference frequency. The power supply range is 2.7 to 5.5 V. ”A” version devices have programmable MCU clock out and reference oscillator disable functions, whereas these functions are always enabled for ”B” version devices. • Complete Expander/Compressor for Superior Noise Rejection • Two PLLs and a LO Suitable for a 900 MHz System • Minimal External Components • Transmit Path Includes Adjustable Gain Amplifier, Filters, Mute, Compressor with Bypass and Limiter • Receive Path Contains Data Slicer, Adjustable Gain Amplifier, Sidetone Attenuator, Filters, Expander with Bypass, Mute, Volume Control and Power Amplifier • Dual A/Ds are Provided to Monitor RSSI and VCC • Independent Power Amplifier with Differential Outputs and Mute • Selectable Frequency for Switched Capacitor Filters, PLLs and the LO • Reference Frequency Source can be a Crystal or System Clock • Serial µP Port to Control Gain, Mute, Frequency Selection, Phase Detector Gain, Power Down Modes, Low Battery Detect and Others • Power Supply Range: 2.7 to 5.5 V • Power Down Modes for Power Conservation Simplified Block Diagram VCC DS In RSSI Tx In Rx Out DS Out Tx Out Audio In MCU Clock Clock Enable Data LO2 Out Amp/Mute Compressor Filter Gain Adj Filter Sidetone Attn Mute Expander Power Amp Programmable Counters 2nd LO PLL #1 PLL #2 Data Slicer Dual A/D MCU Interface LPF+ VCO + Prescaler LPF Tank This device contains 11,108 active transistors.
