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.
The circuit techniques used have been chosen to minimise
external components and at the same time give very high
performance.
