Single Serial Input
PLL Frequency Synthesizer
On-chip 2.5 GHz Prescaler
MB15E07SL
DESCRIPTION
■■■■
The Fujitsu MB15E07SL is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 2.5 GHz prescaler .
The 2.5 GHz prescaler has a dual modulus division ratio of 32/33 or 64/65 enabling pulse s wallowing operation.
The supply voltage range is between 2.4 V and 3.6 V. The MB15E07SL uses the latest BiCMOS process, as a
result the supply current is typically 3.5 mA at 2.7 V. A refined charge pump supplies well-balanced output currents
of 1.5 mA and 6 mA. The charge pump current is selectable by serial data.
MB15E07SL is ideally suited for wireless mobile communications, such as GSM (Global System for Mobile
Communications) and PCS.

FUNCTIONAL DESCRIPTION
■
1.Pulse Swallow Function
The divide ratio can be calculated using the following equation:
fVCO = [(M × N) + A] × fOSC÷ R (A < N)
f
VCO : Output frequency of external voltage controlled oscillator (VCO)
N: Preset divide ratio of binary 11-bit programmable counter (3 to 2,047)
A: Preset divide ratio of binary 7-bit swallow counter (0 ≤ A ≤ 127)
f
OSC : Output frequency of the reference frequency oscillator
R: Preset divide ratio of binary 14-bit programmable reference counter (3 to 16,383)
M: Preset divide ratio of modulus prescaler (32 or 64)
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 LE signal pin is taken
high, stored data is latched according to the control bit data as follows:

(2) 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 (D
(f
O) and the phase comparator output (φR, φP) are re v ersed according to the FC bit. Also, the monitor pin
OUT) output is controlled by the FC bit. The relationship between the FC bit and each of DO, φR, and φP is shown
below .

When designing a synthesizer, the FC pin setting depends on the VCO and LPF characteristics.
* : When the LPF and VCO characteristics are similar
to (1), set FC bit high.
* : When the VCO characteristics are similar to (2), set
FC bit low.

Table 10. PS Pin Setting

The intermittent mode control circuit reduces the PLL power consumption.
By setting the PS pin low , the de vice enters into the power sa ving mode, reducing the current consumption. See
the Electrical Characteristics chart for the specific value.
The phase detector output, Do, becomes high impedance.
For the signal PLL, the lock detector, LD, remains high, indicating a locked condition.
Setting the PS pin high, releases the power saving mode, and the device works nor mally.
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 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.
When power (V
CC) is first applied, the device must be in standby mode, PS = Low, for at least 1 µs.
