s DESCRIPTION
The Fujitsu MB15E05L is serial input Phase Locked Loop (PLL) frequency synthesizer with a 2.0 GHz prescaler. A
64/65 or a 128/129 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 4.0 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, MB15E05L is ideally suitable for digital mobile communications, such as DCS 1800 and PCS 1900.
s FEATURES
• High frequency operation: 2.0 GHz max.
• Low power supply voltage: VCC = 2.7 to 3.6 V
• Very Low power supply current : ICC = 4.0 mA typ. (VCC = 3 V)
• Power saving function : IPS = 0.1 µA typ.(VCC = 3 V)
• Pulse swallow function: 64/65 or 128/129
• 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
• On–chip high performance charge pump circuit and phase comparator, achieving high–speed lock–up and low
phase noise.
• Wide operating temperature: Ta = –40 to 85°C
• Plastic 16-pin SSOP package (FPT-16P-M05) and 16-pin BCC package (LCC-16P-M02)
