s DESCRIPTION
The Fujitsu MB15C103 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 0.9 mA typ.(200MHz) of current realized through the
use of Fujitsu’s CMOS technology.
The MB15C103 is ideally suitable for PDC systems.
s FEATURES
• Low power supply current: ICC = 0.9 mA typ. (VCC = 3 V, 200MHz)
• Pulse swallow function; Prescaler: 16/17
• Setting frequency (Selectable by DIV input.)
– fosc = 12.8 MHz, fIF = 178.00 MHz (DIV = “H”)
– fosc = 12.8 MHz, fIF = 129.55 MHz (DIV = “L”)
• Lock detector
• Low power supply voltage: VCC = 2.4 to 3.6 V
• Wide operating temperature: Ta = –40 to +85°C
