MB15E03SL Single Serial Input PLL Frequency Synthesizer On-chip 1.2 GHz Prescaler The Cypress MB15E03SL is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 1.2 GHz prescaler. The 1.2 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 MB15E03SL uses the latest BiCMOS process, as a result, the supply current is typically 2.0 mA at 2.7 V. A refined charge pump supplies a well balanced output currents of 1.5 mA or 6 mA. The charge pump current is selectable by serial data. Features High frequency operation: 1.2 GHz max Low power supply voltage: V = 2.4 V to 3.6 V CC Ultra Low power supply current:I = 2.0 mA typ. (V = Vp = 2.7 V, Ta = +25C, in locking state) CC CC I = 2.5 mA typ. (V = Vp = 3 V, Ta = +25C, in locking state) CC CC Direct power saving function:Power supply current in power saving mode Typ. 0.1 A (V = Vp = 3 V, Ta = +25C), Max. 10A (V = Vp = 3 V) CC CC Dual modulus prescaler: 64/65 or 128/129 Serial input 14-bit programmable reference divider: R = 3 to 16,383 Serial input programmable divider consisting of: Binary 7-bit swallow counter: 0 to 127 Binary 11-bit programmable counter: 3 to 2,047 Selectable charge pump current On-chip phase control for phase comparator Operating temperature: Ta = 40 to +85C Cypress Semiconductor Corporation 198 Champion Court San Jose, CA 95134-1709 408-943-2600 Document Number: 002-08431 Rev. *A Revised Thursday, December 22, 2016 MB15E03SL Contents Pin Assignments ...............................................................3 Measurement Circuit (for Measuring Input Sensitivity fin/OSCIN) .....................................................15 Pin Description ..................................................................4 Typical Characteristics ...................................................16 Block Diagram ...................................................................5 fin Input Sensitivity .....................................................16 Absolute Maximum Ratings .............................................6 OSCIN Input Sensitivity .............................................16 Recommended Operating Conditions ............................6 Do Output Current .....................................................17 fin Input Impedance ...................................................18 Electrical Characteristics .................................................7 OSCIN Input Impedance ...........................................18 Functional Description .....................................................9 Reference Information ....................................................19 Pulse Swallow Function ...............................................9 Serial Data Input ..........................................................9 Application Example .......................................................22 Do Output Control ......................................................12 Usage Precautions ..........................................................23 Power Saving Mode (Intermittent Mode Control Ordering Information ......................................................23 Circuit) ........................................................................12 Package Dimensions ......................................................24 Serial Data Input Timing .................................................13 Document History ........................................................... 26 Phase Comparator Output Waveform ...........................14 Sales, Solutions, and Legal Information ...................... 27 Document Number: 002-08431 Rev. *A Page 2 of 27
