ACE9030
Radio Interface and Twin Synthesiser
Supersedes February 1997 edition, DS4288 - 1.4
DS4288 - 2.0 January 1998
ACE9030 is a combined radio interface circuit and twin synthesiser, intended for use in a cellular telephone.
The radio interface section contains circuits to monitor and control levels such as transmit power in the telephone, circuits to demodulate the frequency modulated signal to audio, and a crystal oscillator with a frequency multiplier.
The Main synthesiser has normal and fractional-N modes both with optional speed-up to select the desired channel. The Auxiliary synthesiser is used for the transmit-receive offset and for modulation.
Both sections are controlled by a serial bus and have software selected power saving modes for battery economy.
