• Ultra Low power supply current : I_CC = 5.8 mA Typ (V_CC = Vp = 3.0 V, Ta = +25 °C, SW = 0 in IF and RF locking state)
• Direct power saving function : Power supply current in power saving mode
                                                  Typ 0.1 A (V_CC = Vp = 3.0 V, Ta = +25 °C) , Max 10 mA (V_CC = Vp = 3.0 V)
• Fractional function : modulo 3 to 16 programmable (implemented in RF-PLL)
• Dual modulus prescaler : 2500* MHz prescaler (16/17 or 32/33) /600 MHz prescaler (8/9 or 16/17)
• Serial input 14-bit programmable reference divider : R = (RF section 8 bit) 3 to 255, (IF section 14 bit) 3 to 16, 383
• Serial input programmable divider consisting of :
   RF section- Binary 5-bit swallow counter : 0 to 31
                   - Binary 10-bit programmable counter : 18 to 1,023
                   - Binary 4-bit fractional counter numerator : 0 to 15
   IF section - Binary 4-bit swallow counter : 0 to 15
                   - Binary 11-bit programmable counter : 3 to 2,047
• On-chip phase comparator for fast lock and low noise
• Operating temperature : Ta = -40 °C to +85 °C
• Small package Bump Chip Carrier.0 (3.4 mm ´ 3.6 mm * 0.6 mm)

* : In case of fmax = 2500 MHz, the following conditions must be fulfilled. Except for it, fmax is up to 2000 MHz. Prescaler ratio = 32 (N > P) at all divide ratio of used operating frequency. Refer to a calculation formula of divide ratio. f_VCORF = (P*N+A+F/Q) *f_OSC/R

Note : Permanent device damage may occur if the above Absolute Maximum Ratings are exceeded. Functional operation should be restricted to the conditions as detailed in the operational sections of this data sheet. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

WARNING: Semiconductor devices can be permanently damaged by application of stress (voltage, current, temperature, etc.) in excess of absolute maximum ratings. Do not exceed these ratings.

The Fujitsu MB15F86UL is Fractional-N Phase Locked Loop (PLL) frequency synthesizer with fast lock up function.

The Fractional-N PLL of MB15F86UL operating up to 2500* MHz and the integer PLL operating up to 600 MHz are integrated on one chip.

The MB15F86UL is used, as charge pump which is well-balanced output current with 1.5 mA and 6 mA selectable by serial data, direct power save control and digital lock detector. In addition, the MB15F86UL adopts a new architecture to achieve fast lock.

The new package (Thin Bump Chip Carrier20) decreases a mount area of MB15F86UL more than 30% comparing with the former B.C.C.16 (for dual PLL, MB15F03SL) .

The MB15F86UL is ideally suited for wireless mobile communications, such as TDMA or CDMA.
