MB15E05SL
Single Serial Input PLL Frequency Synthesizer
On-chip 2.0 GHz Prescaler
The Cypress MB15E05SL is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 2.0 GHz prescaler. The 2.0 GHz
prescaler has a dual modulus division ratio of 64/65 or 128/129 enabling pulse swallowing operation.
The supply voltage range is between 2.4 V and 3.6 V. The MB15E05SL uses the latest BiCMOS process, as a result the supply cur-
rent is typically 3.0 mA at 2.7 V. A refined charge pump supplies well-balanced output currents of 1.5 mA and 6 mA. The charge
pump current is selectable by serial data.
MB15E05SL is ideally suited for wireless mobile communications, such as GSM (Global System for Mobile Communications) and
PCS.
