FUJITSU SEMICONDUCTOR DATA SHEET DS04-21382-1E ASSP DTS Bi-CMOS Dual Serial Input PLL Frequency Synthesizer MB15F63UL ■ DESCRIPTION MB15F63UL has a 2000 MHz PLL frequency synthesizer with a high-speed frequency switching function based on the Fractional-N PLL (Phase Locked Loop), and 600 MHz Integer-N PLL frequency synthesizer which enables pulse swallow operation. Encased in a subminiature package (thin-BCC20), MB15F63UL has successfully achieved a small thin external form (BCC20 package dimensions: 3.50 mm × 3.50 mm × 0.60 mm). MB15F63UL is suitable for use in digital mobile communication devices such as GSM. ■ FEATURES 100 MHz to 1800 MHz (RF : 2.7 V ≤ Vcc < 2.9 V) / 100 MHz to 2000 MHz (RF : 2.9 V ≤ Vcc ≤ 3.3 V) 50 MHz to 600 MHz (IF) Fractional-N function : Modulo 1048576 (Σ∆ method) : Fractional-N, enabling high-speed PLL lock-up and low phase noise Low voltage operation : Vcc = 2.7 V to 3.3 V Ultra Low power supply current : 6.1 mA Typ (RF) +1.4 mA (IF) Vcc = 3.0 V, Ta = + 25 °C, in locking state Direct power saving function : Power supply current in power saving mode (controllable in external pin) 0.1 µA Typ (Vcc = 3.0 V, Ta = + 25 °C) 10 µA Max (Vcc = 3.0 V) Internal automatic switch changeover circuit (changeover time selectable) Bit function to update the changeover time Constant-current charge pump circuit capable of switching control of the current value through serial data control or internal changeover circuit : For steady-state operation: 94 µA For high-speed changeover: 4.5 mA (Continued) • High frequency operation : • • • • • • Copyright©2006 FUJITSU LIMITED All rights reserved MB15F63UL (Continued) • Open-drain NMOS switch that can be turned on and off from the internal changeover circuit • Prescaler division ratio : 2000 MHz prescaler (16/17/20/21) /600 MHz prescaler (8/9, 16/17) • 29-bit shift register input control • Serial input 14-bit programmable reference divider : Binary 6-bit 1 to 63 (RF side) / Binary 14-bit swallow counter 3 to 16383 (IF side) • Serial input programmable divider consisting of : Binary 4-bit swallow counter 0 to 15 (RF side) / Binary 7-bit swallow counter 0 to 127 (IF side) Binary 7-bit programmable counter 5 to 127 (RF side) /Binary 11-bit swallow counter 3 to 2047 (IF side) • On-chip phase control for phase comparator • Built-in digital locking detector circuit to detect PLL locking and unlocking • Extended operating temperature : Ta = −40 °C to +85 °C 2 MB15F63UL ■ PIN ASSIGNMENTS (TOP VIEW) finIF PSIF 17 OSCin 2 16 VccIF GND 3 15 CLK SW 4 14 Data DoRF 5 13 LE VPRF 6 12 VccRF LD/fout 7 11 finRF VPIF 1 DoIF 20 XfinIF 8 19 9 18 10 XfinRF PSRF GND (LCC-20P-M06) 3 MB15F63UL ■ PIN DESCRIPTIONS Pin no.

It is designed to control the power consumed by the entire circuit block. However, if the circuit starts operating directly from a stop state, the phase relation is undefined, even when the comparison frequency (fp) is the same as the reference frequency (fr) input to the phase comparator. As a result, the phase comparator generates excessive error signals, causing the problem of unlocking the PLL. To solve this problem, the intermittent operation control has been implemented to control fluctuations in the locked frequency by performing forcible phase adjustment at the beginning of operation. • Operation mode The set channel and crystal oscillator circuit are in operation and the PLL performs normal operation. • Power save mode This mode realizes low current consumption by stopping the circuits which will not cause any problem even when stopped. In this condition, the standard consumption current is 0.1 µA per channel with the maximum of 10 µA. At this point, Do and LD are set to the same levels as when the PLL was locked. The Do enters a high impedance state, and the voltage input to the voltage control oscillator (VCO) remains the same as the voltage for operation mode (i.e. locked state) with the time constant of the low pass filter. Therefore, the VCO output frequency can be maintained almost at the same level as the lock frequency. Notes : • When power (VCC) is first applied, the device must be in power saving mode (external pin = L, due to the undefined serial data) . • The serial data input after the power supply became stable, and then the power saving mode is released after completed the data input.

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.

(1) Integer operation when F = 0 When F is set to “0”, the Σ∆ circuit block is stopped completely and the same operation as a normal Integer product is performed. Therefore, the most preferable noise characteristics can be achieved. (2) Generation of spurious signals 1.Spurious signals are generated in the offset part of fp, which is a comparison frequency (equivalent of a reference leak in the integer type). Example: If fosc is set to 13 MHz and R is set to 2 when fvco is 800 MHz in the GSM 800 MHz band, Ntotal becomes 124 and F becomes 0. (Integer mode) Spurious signals are generated at “fp / R = 13 MHz / 2 = 6.5 MHz” offset. (Reference leak) (The waveform resembles that of the reference leakage shown on Ref Leakage of “REFERENCE INFORMATION”. A filter can be used to eliminate the effects.) 2. Due to the Σ∆ circuit operation, spurious signals are generated where “F / Q × fp” or “(Q − F) / Q × fp” is located. Example: fosc = 13 MHz; R = 2 in GSM 800 MHz band: When fvco is 806.2 MHz, Ntotal becomes 142.0307692... and F becomes 32263. Consequently, spurious signals are generated at “F / Q × fp =: 200 kHz” offset. C/N 200 kHz Offset ATTEN 10 dB RL 0 dBm D S VAVG 20 10 dB/ ∆ MKR −82.50 dB 200.0 kHz ∆ MKR 200.0 kHz −82.50 dB CENTER 806.2000 MHz ∗VBW 3.0 kHz ∗RBW 1.0 kHz SPAN 500.0 kHz SWP 1.30 s Adjusting the filter may reduce these spurious signals. Furthermore, modifying R and fr may change the setting value to avoid to generate spurious signals. For example, when fosc = 13 MHz and R = 2, Ntotal becomes 125.0307692…, where fvco is 812.7 MHz. Therefore, F becomes 32263. Spurious signals are supposed to be generated at “F / Q × fp =: 200 kHz” and 200 kHz offset. However, if R is changed to 3, F will become 572683 and “F / Q × fp =: 2.366 MHz” and spurious signals will be the outer frequencies. Therefore, the effects will not be foreseen. 28 MB15F63UL Note that the problem cannot be avoided when the setting value of the swallow counter (A) is odd-numbered (also applicable to the 806.2 MHz environment, used in the above explanation). However, the spurious signals can be reduced by changing fr (reducing it) to limit the band. Note that in this case, the comparison frequency itself changes, resulting in a change in the loop band and deterioration of CN. Therefore,each case should be handled in accordance with the system used.

Excessive spurious signals are generated when setting a binary division such as F/Q = 1/2, 1/4, 1/8… If it is difficult to reduce the excess level, value F can be shifted to the acceptable range of frequency differences to reduce it. Example: Spurious noise is generated on the entire floor when F = 524288 (F/Q = 1/2). Spurious noise is generated on the entire floor when F = 262144 (F/Q = 1/4).
