DESCRIPTION
The Fujitsu MB15C100 series is an exclusive Intermediate Frequency (IF) band Phase Locked Loop (PLL) frequency
synthesizer with pulse swallow operation. It can operate maximum at 500 MHz.
The reference divider and comparison divider have fixed divide ratios, so that it is not required to set the divide ratios
by a
controller externally. Because the dividers are designed by means of MASK ROM method, a customer can
chose them optionally. SSOP-8 and BCC-16 plastic packages are available.
All of the above features help a system designer for easier as well as compact layout work.
It operates with a supply voltage of 3.0 V typ. and dissipates 1.2 mA typ. (@ 300 MHz) of current realized through
the use of CMOS technology.

Charge pump options:
- L type ; Low sensitivity charge pump for direct modulation. (IOH/IOL = 1.5 mA @ V
CC
= 3.0 V)
- H type ; Super charger circuit for High speed tuning. (IOH/IOL = 6.0 mA @ V
CC
= 3.0 V)
Low power supply voltage: V
CC
= 2.4 V min.
