The supply voltage range is between 2.4 V and 3.6 V. The MB15E07SL uses the latest BiCMOS process, as a result the supply current is typically 3.5 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. MB15E07SL is ideally suited for wireless mobile communications, such as GSM (Global System for Mobile Communications) and PCS. ¦ nnnn FEATURES • High frequency operation: 2.5 GHz Max • Low power supply voltage: VCC = 2.4 to 3.6 V • Ultra Low power supply current: ICC = 3.5 mA Typ (VCC = Vp = 2.7 V, Ta = +25° C, in locking state) ICC = 4.0 mA Typ (VCC = Vp = 3.0 V, Ta = +25° C, in locking state) • Direct power saving function: Power supply current in power saving mode Typ 0.1 m A (VCC = Vp = 3.0 V, Ta = +25° C), Max 10 m A (VCC = Vp = 3.0 V) (Continued) ¦ nnnn PACKAGES 16-pin plastic SSOP 16-pad plastic BCC (FPT-16P-M05) (LCC-16P-M06) MB15E07SL (Continued) • Dual modulus prescaler: 32/33 or 64/65 • 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 • Software selectable charge pump current • On-chip phase control for phase comparator • Operating temperature: Ta = –40 to +85° C • Pin compatible with MB15E07, MB15E07L n PIN ASSIGNMENTS OSCIN OSCOUT VP VCC DO GND Xfin fin f R f P LD/fout ZC PS LE Data Clock 16 15 14 13 12 11 10 9 1 2 3 4 5 6 7 8 OSCOUT VP VCC DO GND Xfin f P LD/fout ZC PS LE Data OSCIN f R fin Clock 1 2 3 4 5 6 7 8 9 10 11 12 13 141516 (FPT-16P-M05) (LCC-16P-M06) 16-pin SSOP 16-pad BCC Top view Top view MB15E07SL n PIN DESCRIPTIONS Pin no.

Connection to a TCXO. 2 1 OSCOUT O Oscillator output. 3 2 VP – Power supply voltage input for the charge pump. 4 3 VCC – Power supply voltage input. 5 4 DO O Charge pump output. Phase of the charge pump can be selected via programming of the FC bit. 6 5 GND – Ground. 7 6 Xfin I Prescaler complementary input, which should be grounded via a capacitor. 8 7 fin I Prescaler input. Connection to an external VCO should be done via AC coupling. 9 8 Clock I Clock input for the 19-bit shift register. Data is shifted into the shift register on the rising edge of the clock. (Open is prohibited.) 10 9 Data I Serial data input using binary code. The last bit of the data is a control bit. (Open is prohibited.) 11 10 LE I Load enable signal input. (Open is prohibited.) When LE is set high, the data in the shift register is transferred to a latch according to the control bit in the serial data. 12 11 PS I Power saving mode control.
