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.
