Built-in IF Band Voltage Controlled Oscillator
Mask ROM Frequency Synthesizer
MB15C703
■ 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.
■ FEATURES
• Pulse swallow function (counter type of MB15C103)
• Setting frequency

• 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)

• Wide operating temperature: −20 °C to +85 °C
• High-speed synchronization charge pump (IOH = −4.5 mA, IOL = 4.5 mA at PLLVDD = 2.5 V typ.)
• Oscillation frequency can be arranged by the number of the external circuit.

Notes : • Phase error detection range: −2π to +2π
• Spikes on Do pulse during locking state are output to prevent dead zone
• LD output becomes low when phase error 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] (Ex.) fOSC = 12.8 MHz : tWU ≥ 625.0 ns
