Single Serial Input
PLL Frequency Synthesizer
On-Chip 2.5 GHz Prescaler
MB15E07
s DESCRIPTION
The Fujitsu MB15E07 is serial input Phase Locked Loop (PLL) frequency synthesizer with a 2.5 GHz prescaler.
A 32/33 or a 64/65 can be selected for the prescaler that enables pulse swallow operation.
The latest BiCMOS process technology is used, resuItantly a supply current is limited as low as 8 mA typ. This
operates with a supply voltage of 3.0 V (typ.)
Furthermore, a super charger circuit is included to get a fast tuning as well as low noise performance. As a result
of this, MB15E07 is ideally suitable for digital mobile communications, such as GSM (Global System for Mobile
Communications).
s FEATURES
• High frequency operation: 2.5 GHz max (@ P= 64/65)
1.8 GHz max (@P = 32/33)
• Low power supply voltage: VCC = 2.7 to 3.6 V
• Very Low power supply current : ICC = 8.0 mA typ. (VCC = 3 V)
• Power saving function : IPS = 0.1 µA typ.
• Pulse swallow function: 32/33 or 64/65
• Serial input 14-bit programmable reference divider: R = 5 to 16,383
• Serial input 18-bit programmable divider consisting of:
- Binary 7-bit swallow counter: 0 to 127
- Binary 11-bit programmable counter: 5 to 2,047
• Wide operating temperature: Ta = –40 to 85°C
• Plastic 16-pin SSOP package (FPT-16P-M05)
