ASTRO-NT
(for RF front-end LSI-Based on PLL, Analog Macro)
MB15G000 Series
s
DESCRIPTION
The ASTRO-NT* is a new technology to correspond to the demand of high performance RF LSI. The technology
stands on a macro concept and create a custom LSI ideal for use in high frequency front-end circuit such as VCO,
amplifier, mixer and I/Q modulator devices.
The chip can be built by combining macros, in accordance with user's demand function and characteristic.
FUJITSU prepares standard RF macros. They are well finished in design and layout to fulfil good performance
by function that a master slice method can not achive. It is possible to modify RF macro in response to user's
demand.
This LSI series uses FUJITSU's latest BiCMOS process technology for low current consumption. In addition,
many types of packages are available that makes it possible to find a proper size package for different circuit
integration levels.
ASTRO-NT is ideal for applications with RF or IF signal, particularly mobile communication devices operating
such as PDC, PHS, GSM, DCS, PCS and so on.

RECOMMENDED OPERATING CONDITIONS
*1:Voltage values are based on GND = 0 V
*2:The range of operating voltage should be defined depends on circuit configuration.
For models not using standard 3V or 5V specifications, maximum ratings and recommended operating conditions
are set according to circuit use.
*3:Using 3V macro specifications
*4:Using 5V macro specifications
WARNING: The recommended operating conditions are required in order to ensure the normal operation of the
semiconductor device. All of the device's electrical characteristics are warranted when the device is
operated within these ranges.
Always use semiconductor devices within their recommended operating condition ranges. Operation
outside these ranges may adversely affect reliability and could result in device failure.
No warranty is made with respect to uses, operating conditions, or combinations not represented on
the data sheet. Users considering application outside the listed conditions are advised to contact their
FUJITSU representatives beforehand.

MACRO DESCRIPTIONS
1.
Prescaler
Divides the reference frequency by any given value and outputs the resulting frequency. Choice of two -modulus
or fixed output mode.
2.
PLL
Phase comparator
The phase comparator has a phase detection range of 2
to +2
, and is designed to eliminate blind spots in
phase comparison by output of a margin-of-error signal to the charge pump even when the phase difference is
zero. Phase comparator characteristics can also be tuned to the polarity of VCO.
Counters
The divide ratios of the comparator-side counter and reference-side counter can be either programmable or fixed.
Charge pump
The "H" level output voltage from the charge pump is determined by power supply voltage. Charge pump
characteristics for the sending and receiving systems can be optimized for each specific application.
For example, when FM modulation is applied directly to the VCO signal, charge pump characteristic can be
adjusted for lower speeds in order to reduce the sensitivity of the synthesizer loop so that output does not track
the modulation.
High speed lock-up circuit
This circuit is specially designed for faster lock-up speeds.
Intermittent operation control circuit
This on-chip power-saving function reduces circuit current flow in standby status, enabling devices to operate
with less power demand. A special circuit is built in to prevent excessive error signal from increasing lock-up
delay during the transition from power-saving mode to operating mode.
