General Description
The DS8911 is a digital Phase-Locked Loop (PLL) frequency synthesizer intended for use as a Local Oscillator (LO) in electronically tuned radios The device is used in conjunction with a serial data controller a loop filter some varactor diodes and several passive elements to provide the local oscillator function for both AM and FM tuning The conventional superheterodyne AM receiver utilizes a low IF or down conversion tuning approach whereby the IF is chosen to be below the frequencies to be received The DS8911 PLL on the other han...
