IF Band PLL Frequency Synthesizer
MB15C103
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 +85C

High impedance
Note: * Phase error detection range: -2 to +2 * 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, fosc = 12.8 MHz) tWL < 16/fosc (s) (e. g. tWL < 1250.0ns, fosc = 12.8 MHz)
