Description



Features:

<<PLL>>
• Pulse swallow function
• 400 MHz High-speed Prescaler : 8/9, 16/17, 32/33
• MASK ROM optinal the comparison and reference dividers :
   Comparison counter : Main counter : 5 to 4095, Swallow counter : 0 to 31
   Reference counter : 5 to 4095 (up to 26 MHZ)
• Lock detector circuit: Digital lock detector circuit which is "H" level when PLL is locked.
• Charge pump options :
   H type: Super charger circuit for high speed tuning. (IOH = -4.5 mA, IOL = 4.5 mA at PLLVDD = 2.5 V)
   L type : Low sensitivity charge pump for direct modulation. (IOH = -1.125 mA, IOL = 1.125 mA at PLLVDD = 2.5 V)
<<VCO>>
• Integrates vari-cap for VCO
• Operating frequency can be arranged by the number of the external inductor and capacitor connected TANK circuit
<<COMMON>>
• Low power supply voltage : 2.3 V to 2.7 V
• Low power supply current : 4.5 mA typ. (PLLVDD = VCOVDD = 2.5 V, fvco = 400 MHz)
• Operating temperature : -20 °C to +85 °C

Description

MB15C700 series 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 of MB15C700 can operate option oscillation frequency by an external inductance and capacitor. The PLL reference divider ratio and comparison divider ratio are fixed , so that it is not required to set the divider ratios by a microcontroller externally. BCC-20 plastic package is miniaturized the device and makes it easier to design. MB15C700 operates with a supply voltage of 2.5 V typ. (PLLVDD, VCOVDD) and low power consumption current 4.5 mA typ. (PLL + VCO at 400 MHz) is realized by pure- CMOS technology.
