s DESCRIPTION
MB15C703 is a Phase Locked Loop (PLL) frequency synthesizer of pulse swallow operation with built-in VCO
suitable for Intermediate Frequency band synthesizer of mobile phones.
The VCO can operate option oscillation frequency by an external inductance and capacitor. The PLL reference
divide ratio and comparison divider ratio are fixed so that it is not required to set the divider ratios by a controller
externally. BCC-20 plastic package miniaturized the device and makes it easier to design.
It operates with a supply voltage of 2.5 V typ. (PLLVDD, VCOVDD) and low power consumption current 2.5mA
typ. is realized by pure-CMOS.
