PLL Frequency Synthesizer
MB15C101
■ 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: ICC = 1.0 mA typ. (VCC = 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: VCC = 2.4 V min.
• Wide operating temperature: Ta = –40 to +85°C

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.

■ FUNCTIONAL DESCRIPTIONS
Two different frequencies can be selected by Div input “H” or “L”.
The divide ratios are calculated using the following equation:
fVCO = {(P × N) + A} × fOSC ÷ R

High impedance
Note: • Phase error detection range: –2π to +2π
• Pulses on Do output signal during locked state are output to prevent dead zone.
• LD output becomes low when phase is tWU or more. LD output becomes high when phase error is tWL or
less and continues to be so for three cycles or more.
• tWU and tWL depend on OSCin input frequency.
tWU > 8/fosc (s) (e. g.tWU > 625.0ns, foscin = 12.8 MHz)
tWL < 16/fosc (s) (e. g. tWL < 1250.0ns, foscin = 12.8 MHz)
