MB15C101

■ DESCRIPTION

The Fujitsu Microelectronics MB15C101 is an exclusive Int ermediate Frequency (IF) band Phase Locked Loop (PLL)
frequency synthesizer with pulse swallow operation. The r eference 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 Microelectronics’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: V

• Wide operating temperature: Ta = –40 to +85°C

■ FUNCTIONAL DESCRIPTIONS

Two different frequencies can be selected by Div input “H” or “L”.
The divide ratios are calculated using the following equation:

f

VCO = {(P × N) + A} × fOSC ÷ R (A < N)

less and continues to be so for three cycles or more.
