IF Band
PLL Frequency Synthesizer
MB15C101
■ DESCRIPTION
The Fujitsu Microelectronics 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 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
CC = 2.4 V min.
• Wide operating temperature: Ta = –40 to +85°C
