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.
