DESCRIPTION
The Fujitsu MB15C101 is an exclusive Intermediate Frequency (IF) band Phase Locked Loop (PLL) frequency
synthesizer 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 1.0 mA typ.(270MHz) of current realized through the
use of Fujitsu’s CMOS technology.
The MB15C101 is ideally suitable for PHS systems.

FEATURES
• Low power supply current: I
CC
= 1.0 mA typ. (V
CC
= 3 V, 270MHz)
• Pulse swallow function; Prescaler: 16/17
• Setting frequency (Selectable by Div input.)
– fosc = 19.2 MHz, fIF = 233.15 MHz (Div = “H”)
– fosc = 19.2 MHz, fIF = 259.20 MHz (Div = “L”)
• Lock detector
• Low power supply voltage: V
CC
= 2.4 V min.
• Wide operating temperature: Ta = –40 to +85°C

No connection
Power supply voltage input (2.4 V to 3.6 V).
Charge pump output
Ground
Prescaler input. Connection should be with AC coupling.
Divide ratio switching input. Two kinds of divide ratios are
selectable by Div input “H” or “L”.
Test purpose output. This pin is an open drain output so that
should be left open usually.
Lock detector output.
LD = H ; Lock
LD = L ; Unlock
Reference counter input. Connection should be with AC
coupling.

Handling Precautions
• This device should be transported and stored in anti-static containers.
• This is a static-sensitive device; take proper anti-ESD precautions. Ensure that personnel and equipment are
properly grounded. Cover workbenches with grounded conductive mats.
• Always turn the power supply off before inserting or removing the device from its socket.
• Protect leads with a conductive sheet when handling or transporting PC boards with devices.
