Dual Serial Input PLL Frequency Synthesizer
MB15F76UL
s DESCRIPTION
The Fujitsu MB15F76UL is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 6.0 GHz and a 1.5 GHz prescalers. Both prescalers for RF and IF have a 1/4 divider. A 16/17 or a 32/33 for the 6.0 GHz prescaler, and a 4/5 or a 8/9 for the 1.5 GHz prescaler can be selected for the prescaler that enables pulse swallow operation. The BiCMOS process is used, as a result a supply current is typically 8.5 mA at 3.0 V. The supply voltage range is from 2.5 V to 3.6 V. A refined charge pump supplies well-balanced output current with 1.5 mA and 6 mA selectable by serial date. The pin assignments are is the same as the MB15F78UL. Fast locking is achieved for adopting the new circuit. The new package (BCC20) decreases a mount area of MB15F76UL more than 30% comparing with the former BCC16 (for dual PLL) .

Note : * 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. * Although this device contains an anti-static element to prevent electrostatic breakdown and the circuitry has been improved in electrostatic protection, observe the following precautions when handling the device. * When storing and transporting the device, put it in a conductive case. * Before handling the device, confirm the (jigs and) tools to be used have been uncharged (grounded) as well as yourself. Use a conductive sheet on working bench. * Before fitting the device into or removing it from the socket, turn the power supply off. * When handling (such as transporting) the device mounted board, protect the leads with a conductive sheet. 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.

3. Power Saving Mode (Intermittent Mode Control Circuit)
Status Normal mode Power saving mode PS pin
H L
The intermittent mode control circuit reduces the PLL power consumption. By setting the PS pin low, the device enters into the power saving mode, reducing the current consumption. See the Electrical Characteristics chart for the specific value. The phase detector output, Do, becomes high impedance. For the dual PLL, the lock detector, LD, is as 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 startup 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 comparaor 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. * PS pin must be set "L" at Power-ON.

4. Serial Data Input Timing
Divide ratio is performed through a serial interface using the Data pin, Clock pin, and LE pin. Setting data is read into the shift register at the rise of the Clock signal, and transferred to a latch at the rise of the LE signal.

s USAGE PRECAUTIONS
(1) VCCRF, VpRF, VCCIF and VpIF must be 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
