(MC33411A/B) ANALOG CORDLESS PHONE BASEBAND

www.DataSheet4U.com Order this document by MC33411A/D MC33411A/B 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. 900 MHz ANALOG CORDLESS PHONE BASEBAND WITH COMPANDER SEMICONDUCTOR TECHNICAL DATA • • • • • • • • • • • • 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 DS In VCC RSSI Tx In Data Slicer Dual A/D Amp/Mute Compressor Filter Gain Adj Filter Sidetone Attn Mute Expander Power Amp MCU Interface Programmable Counters PLL #1 PLL #2 2nd LO 48 1 FTA SUFFIX PLASTIC PACKAGE CASE 932 (LQFP–48) ORDERING INFORMATION Device MC33411AFTA MC33411BFTA Operating Temperature TA = –20 to 70°C Package LQFP–48 DS Out Tx Out Audio In MCU Clock Clock Enable Data Rx Out Tank LO2 Out This device contains 11,108 active transistors.
