DESCRIPTION
The Fujitsu MB15S01 is an exclusive Intermediate Frequency (IF) band Phase Locked Loop (PLL) frequency syn-
thesizer with pulse swallow operation. The reference divider and comparison divider have fixed divide ratios, so that
it is not required to set the divide ratios by a microcontroller externally.
It operates with a supply voltage of 3.0 V typ. and dissipates 3.5 mA typ. of current realized through the use of
Fujitsu’s Bi-CMOS technology.
RF synthesizer block of digital cellular phones can be realized easily as well as compactly with MB15S01 and
MB1517A (2.0 GHz; SSOP-16), which is Fujitsu’s standard product developped for digital cellular phones.
The MB15S01 is ideally suitable for PHS systems.
