MB15C703
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.
s FEATURES
* Pulse swallow function (counter type of MB15C103) * Setting frequency Setting frequency 129.55 MHz Reference frequency 12.8 MHz
* Lock detector circuit: Digital lock detector circuit which is "H" level when PLL is locked. * Low power supply voltage: 2.3 V to 2.7 V * Low power supply current: 2.5 mA typ. (PLLVDD = VCOVDD = 2.5 V, fvco = 129.55 MHz)
