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

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.
s RECOMMENDED OPERATING CONDITIONS
Parameter Power supply voltage Input voltage Operating temperature Handling Precautions (1) VCCRF, VpRF, VCCIF and VpIF must supply equal voltage. Even if either RF-PLL or IF PLL is not used, power must be supplied to VCCRF, VpRF, VCCIF and VpIF to keep them equal. It is recommended that the non-use PLL is controlled by power saving function. (2) To protect against damage by electrostatic discharge, note the following handling precautions : -Store and transport devices in conductive containers. -Use properly grounded workstations, tools, and equipment. -Turn off power before inserting or removing this device into or from a socket. -Protect leads with conductive sheet, when transporting a board mounted device.

WARNING: The recommended operating conditions are required in order to ensure the normal operation of the semiconductor device. All of the device's electrical characteristics are warranted when the device is operated within these ranges. Always use semiconductor devices within their recommended operating condition ranges. Operation outside these ranges may adversely affect reliability and could result in device failure. No warranty is made with respect to uses, operating conditions, or combinations not represented on the data sheet. Users considering application outside the listed conditions are advised to contact their FUJITSU representatives beforehand.

* Power Saving Mode (Intermittent Mode Control) * PS Pin Setting PS pin H L Normal mode Power saving mode
Status
The intermittent mode control circuit reduces the PLL power consumption. By setting the PS pin low, the device enters the power saving mode, reducing the current consumption. See "s ELECTRICAL CHARACTERISTICS" for the specific value. The phase detector output, Do, becomes high impedance. For the dual PLL, the lock detector, LD, is shown in the LD Output Logic table. Setting the PS pin high releases the power saving mode, and the device works normally. The intermittent mode control circuit also ensures a smooth start-up when the device returns to normal operation. When the PLL is returned to normal operation, the phase comparator output signal is unpredictable. This is because of the unknown relationship between the comparison frequency (fp) and the reference frequency (fr) which can cause a major change in the comparator output, resulting in a VCO frequency jump and an increase in lockup time. To prevent a major VCO frequency jump, the intermittent mode control circuit limits the magnitude of the error signal from the phase detector when it returns to normal operation. Notes: *When power (VCC) is first applied, the device must be in standby mode and PS = Low, for at least 1 s. *PS pin must be set "L" for Power ON and then the PS mode should be removed after input serial data.

Notes: * Phase error detection range = -2 to +2 * Pulses on DoIF/RF signals are output to prevent dead zone. * LD output becomes low when phase error is tWU or more. * LD output becomes high when phase error is tWL or less and continues to be so for three cycles or more. * tWU and tWL depend on OSCIN input frequency as follows. tWU 2/fosc [s] : i.e. tWU 153.8 ns when fosc = 13.0 MHz tWU 4/fosc [s] : i.e. tWL 307.7 ns when fosc = 13.0 MHz
