On-Chip 2.0 GHz Prescaler
MB15E05L
s DESCRIPTION
The Fujitsu MB15E05L is serial input Phase Locked Loop (PLL) frequency synthesizer with a 2.0 GHz prescaler. A 64/65 or a 128/129 can be selected for the prescaler that enables pulse swallow operation. The latest BiCMOS process technology is used, resuItantly a supply current is limited as low as 4.0 mA typ. This operates with a supply voltage of 3.0 V (typ.) Furthermore, a super charger circuit is included to get a fast tuning as well as low noise performance. As a result of this, MB15E05L is ideally suitable for digital mobile communications, such as DCS 1800 and PCS 1900.

s FUNCTION DESCRIPTIONS
1. Pulse Swallow Function
The divide ratio can be calculated using the following equation: fVCO = [(M x N) + A] x fOSC / R (A < N) fVCO : Output frequency of external voltage controlled oscillator (VCO) N : Preset divide ratio of binary 11-bit programmable counter (5 to 2,047) A : Preset divide ratio of binary 7-bit swallow counter (0 A 127) fOSC : Output frequency of the reference frequency oscillator R : Preset divide ratio of binary 14-bit programmable reference counter (5 to 16,383) M : Preset divide ratio of modules prescaler (64 or 128)
2. Serial Data Input
Serial data is processed using the Data, Clock, and LE pins. Serial data controls the programmable reference divider and the programmable divider separately. Binary serial data is entered through the Data pin. One bit of data is shifted into the shift register on the rising edge of the clock. When the load enable pin is high, stored data is latched according to the control bit data as follows:

Relation between the FC input and phase characteristics The FC bit changes the phase characteristics of the phase comparator. Both the internal charge pump output level (DO) and the phase comparator output (R, P) are reversed according to the FC bit. Also, the monitor pin (fOUT) output is controlled by the FC bit. The relationship between the FC bit and each of DO, R, and P is shown below.

3. Power Saving Mode (Intermittent Mode Control Circuit)
Setting a PS pin to Low, the IC enters into power saving mode resultatly current consumption can be limited to 10 A (max.). Setting PS pin to High, power saving mode is released so that the IC works normally. In addition, the intermittent operation control circuit is included which helps smooth start up from the power saving mode. In general, the power consumption can be saved by the intermittent operation that powering down or waking up the synthesizer. Such case, if the PLL is powered up uncontrolled, the resulting phase comparator output signal is unpredictable due to an undefined phase relation between reference frequency (fr) and comparison frequency (fp) and may in the worst case take longer time for lock up of the loop. To prevent this, the intermittent operation control circuit enforces a limited error signal output of the phase detector during power up, thus keeping the loop locked. During the power saving mode, the corresponding section except for indispensable circuit for the power saving function stops working, then current consumption is reduced to 10 A (max.). At that time, the Do and LD become the same state as when a loop is locking. That is, the Do becomes high impedance. A VCO control voltage is naturally kept at the locking voltage which defined by a LPF"s time constant. As a result of this, VCO's frequency is kept at the locking frequency. Note: * While the power saving mode is executed, ZC pin should be set at "H" or open. If ZC is set at "L" during power saving mode, approximately 10 A current flows. * PS pin must be set "L" at Power-ON. * The power saving mode can be released (PS : L H) 1s later after power supply remains stable. * During the power saving mode, it is possible to input the serial data.

Notes: 1. Phase error detection range: -2 to +2 2. Pulses on Do output signal during locked state are output to prevent dead zone. 3. LD output becomes low when phase 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. 4. tWU and tWL depend on OSCin input frequency.
