FUJITSU SEMICONDUCTOR DATA SHEET DS04-21381-1E ASSP Dual Serial Input PLL Frequency Synthesizer MB15F74UV ■ DESCRIPTION The Fujitsu MB15F74UV is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 4000 MHz and a 2000 MHz prescalers. A 64/65 or a 128/129 for the 4000 MHz prescaler, and a 32/33 or a 64/65 for the 2000 MHz 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 9.0 mA at 3.0 V. The supply voltage range is from 2.7 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 serial data format is the same as MB15F74UL. Fast locking is achieved for adopting the new circuit. MB15F74UV is in the small package (BCC18) which decreases a mount area of MB15F74UV about 50% comparing with the former BCC20 (for dual PLL) . ■ FEATURES • High frequency operation : RF synthesizer : 4000 MHz Max : IF synthesizer : 2000 MHz Max • Low power supply voltage : VCC = 2.7 V to 3.6 V • Ultra low power supply current : ICC = 9.0 mA Typ (VCC = 3.0 V, Ta = +25 °C, SWIF = SWRF = 0 in IF/RF locking state) (Continued) ■ PACKAGE 18-pin plastic BCC (LCC-18P-M05) MB15F74UV (Continued) • Direct power saving function : Power supply current in power saving mode Typ 0.1 µA (VCC = 3.0 V, Ta = +25 °C at 1 system) Max 10 µA (VCC = 3.0 V at 1 system) • Software selectable charge pump current : 1.5 mA/6.0 mA Typ • Dual modulus prescaler : 4000 MHz prescaler (64/65 or128/129) /2000 MHz prescaler (32/33 or 64/65) • 23 bit shift register • Serial input binary 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 • Built-in high-speed tuning, low-noise phase comparator, current-switching type constant current circuit • On-chip phase control for phase comparator • On-chip phase comparator for fast lock and low noise • Built-in digital locking detector circuit to detect PLL locking and unlocking • Operating temperature : Ta = −40 °C to +85 °C • Serial data format compatible with MB15F74UL • Ultra small package BCC18 (2.4 mm × 2.7 mm × 0.45 mm) ■ PIN ASSIGNMENTS TOP VIEW Clock OSCIN Data GND 1 18 17 16 15 finIF XfinIF GNDIF VCCIF 2 3 4 5 14 13 12 DOIF 6 7 8 9 finRF XfinRF 11 GNDRF VCCRF 10 DORF PSIF PSRF LD/fout (LCC-18P-M05) 2 LE MB15F74UV ■ PIN DESCRIPTION Pin no.

Power Saving Mode (Intermittent Mode Control Circuit) Status PS pin Normal mode H Power saving mode 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. OFF V CC ON tV ≥ 1 µs Clock Data LE tPS ≥ 100 ns PS (1) (2) (3) (1) PS = L (power saving mode) at Power-ON (2) Set serial data at least 1 µs after the power supply becomes stable (VCC ≥ 2.2 V) . (3) Release power saving mode (PSIF, PSRF : “L” → “H”) at least 100 ns later after setting serial data. 11 MB15F74UV 4. Serial Data 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. The following diagram shows the data input timing. 1st data 2nd data Invalid data Control bit Data MSB LSB Clock t1 t2 t3 t6 t7 LE t4 Parameter Min Typ Max Unit Parameter Min Typ Max Unit t1 20 ns t5 100 ns t2 20 ns t6 20 ns t3 30 ns t7 100 ns t4 30 ns Note : LE should be “L” when the data is transferred into the shift register. 12 t5 MB15F74UV ■ PHASE COMPARATOR OUTPUT WAVEFORM fr IF/RF fp IF/RF t WU t WL LD (FC bit = “1”) D o IF/RF H Z L (FC bit = “0”) H D o IF/RF Z L • LD Output Logic IF-PLL section RF-PLL section LD output Locking state/Power saving state Locking state/Power saving state H Locking state/Power saving state Unlocking state L Unlocking state Locking state/Power saving state L Unlocking state Unlocking state L Notes : • Phase error detection range = −2π to +2π • Pulses on DoIF/RF signals during locking state 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 : e.g. tWU ≥ 156.3 ns when fosc = 12.8 MHz tWU ≤ 4/fosc : e.g. tWL ≤ 312.5 ns when fosc = 12.8 MHz 13 MB15F74UV ■ TEST CIRCUIT (for Measuring Input Sensitivity fin/OSCIN) S.G. 1000 pF 50 Ω S.G. 1000 pF Controller (divide ratio setting) 50 Ω OSCIN Clock Data LE GND S.G. 1 18 17 16 15 1000 pF finIF 50 Ω XfinIF 2 14 3 13 1000 pF MB15F74UV 4 12 5 11 GNDIF DoIF finRF 0.1 µF 1000 pF XfinRF GNDRF VCCRF VCCIF VCCIF VCCRF 6 7 PSIF 8 9 LD/ fout 10 DoRF PSRF 0.1 µF Oscilloscope 14 MB15F74UV ■ TYPICAL CHARACTERISTICS 1. fin input sensitivity RF-PLL input sensitivity vs. Input frequency Ta = +25 C 10 PfinRF [dBm] 0 VCC = 2.7 V Catalog guaranteed range −10 VCC = 3.0 V −20 VCC = 3.6 V −30 SPEC −40 −50 1500 2000 2500 3000 3500 4000 4500 5000 finRF [MHz] IF-PLL input sensitivity vs. Input frequency 10 Ta = +25 C PfinIF [dBm] 0 VCC = 2.7 V Catalog guaranteed range −10 VCC = 3.0 V VCC = 3.6 V −20 SPEC −30 −40 −50 0 500 1000 1500 2000 2500 3000 finIF [MHz] 15 MB15F74UV 2.

Even if either RF-PLL or IF-PLL is not used, power must be supplied to VCCRF and VCCIF 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 ■ ORDERING INFORMATION Part number MB15F74UVPVB Package Remarks 18-pin plastic BCC (LCC-18P-M05) 23 MB15F74UV ■ PACKAGE DIMENSION 18-pin plastic BCC (LCC-18P-M05) 15 2.70±0.10 (.106±.004) INDEX AREA 0.45±0.05 (.018±.002) (Mount height) 10 10 2.01(.079) TYP 2.40±0.10 (.094±.004) 0.45(.018) TYP. 1 0.075±0.025 (.003±.001) (Stand off) 6 2.31(.090) TYP 0.45(.018) TYP. 0.90(.035) REF 1.90(.075) REF "A" "B" "C" 6 15 1.35(.053) REF 1 2.28(.090) REF Details of "A" part 0.05(.002) 0.14(.006) MIN.
