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.

Figure 4 - Typical VDD local decoupling networks without series resistors
Figure 5 - Typical VDD local decoupling networks with series resistors
at all times including during power on and off ramping. As the
current taken through these V
DD
's is significantly less than
through the other V
DD
's this requirement can be easily met by
directly connecting all V
DD
pins to a common point on the circuit
board but with the decoupling capacitors distributed to
minimise cross-talk caused by common mode currents. If low
value series resistors are to be included in the V
DD
connec-
tions, with decoupling capacitors by the ACE9030 pins to
further reduce interference, the V
DDSUB
and V
DDSUB2
pins should
not have such a resistor in order to guarantee that their voltage
is not slowed down at power-on. Power switches to DOUT0
and DOUT1 are supplied from V
DDX
and are specified for a total
current of up to 40 mA so any resistor in the V
DDX
connection
must be very low, around 1
, in order to avoid excessive
voltage drop; it is recommended that this supply has no series
resistor. These two methods are shown in circuit diagrams,
figures 4 and 5. In both circuits the main V
DD
must also have
good decoupling.

Notes
1. The sleep current is specified with the crystal oscillator (XO) and the OSC8 oscillator and PLL running as these are normally needed to provide
the clock to the system controller.
2. The terms f

, f
MAIN
, and f
AUX
refer to the frequencies of the Reference inputs (Crystal oscillator, pins CIN1 and CIN2), the Main synthesiser
inputs (pins FIM and FIMB) and the Auxiliary synthesiser inputs (pins FIA and FIAB) respectively.
