PEREGRINE PE9763EK

Product Specification
PE9763
3.2 GHz Delta-Sigma modulated
Fractional-N Frequency Synthesizer
for Low Phase Noise Applications
Product Description
Peregrine’s PE9763 is a high performance fractional-N PLL
capable of frequency synthesis up to 3.2 GHz. The device is
designed for superior phase noise performance while providing
an order of magnitude reduction in current consumption, when
compared with the existing commercial space PLLs.
The PE9763 features a 10/11 dual modulus prescaler,
counters, a delta sigma modulator, a phase comparator and a
charge pump as shown in Figure 1. Counter values are
programmable through either a serial interface or directly hardwired.
PE9763 is optimized for commercial space applications. Single
Event Latch up (SEL) is physically impossible and Single Event
Upset (SEU) is better than 10-9 errors per bit / day. Fabricated
in Peregrine’s patented UTSi® (Ultra Thin Silicon) CMOS
technology, the PE9763 offers excellent RF performance and
intrinsic radiation tolerance.

PE9763
Product Specification
Functional Description
The PE9763 consists of counters, a prescaler, an
18-bit delta-sigma modulator (DSM), a phase
detector and a charge pump. The dual modulus
prescaler divides the VCO frequency by either 10
or 11, depending on the value of the modulus
select. Counters “R” and “M” divide the reference
and prescaler output, respectively, by integer
values stored in a 20-bit register. An additional
counter (“A”) is used in the modulus select logic.
The DSM modulates the “A” counter outputs in
order to achieve the desired fractional step.
The phase-frequency detector generates up and
down frequency control signals. These signals can
be configured to drive a tri-state charge pump.
Data is written into the internal registers via the
three wire serial bus. There are also various
operational and test modes and a lock detect
output

Product Specification
Main Counter Chain
Normal Operating Mode
Setting the Pre_en control bit “low” enables the
÷10/11 prescaler. The main counter chain then
divides the RF input frequency (Fin) by an integer
or fractional number derived from the values in the
“M”, “A” counters and the DSM input word K. The
accumulator size is 18 bit, so the fractional value
is fixed from the ratio K/218. There is an additional
bit in the DSM that acts like an extra bit (19th bit).
This bit is enabled by asserting the pin
RAND_SEL to “high”. Enabling this bit has the
benefit of reducing the spurious levels. However,
a small frequency offset will occur. This positive
frequency offset is calculated with the following
equation.
foffset = (fr / (R + 1)) / 219
(1)
All of the following equations do not take into
account of this frequency offset. If this offset is
important to a specific frequency plan, appropriate
account needs to be taken.
In the normal mode, the output from the main
counter chain (fp) is related to the VCO frequency
(Fin) by the following equation:
fp = Fin / [10 x (M + 1) + A + K/218]
where A ≤ M + 1, 1 ≤ M ≤ 511
(2)
Fin = (M + 1) x (fr / (R+1))
where 1 ≤ M ≤ 511
(4)
(*) Only integer mode
In frequency bypass mode, neither A counter or K
counter is used. Therefore, only integer-N
operation is possible.
Reference Counter
The reference counter chain divides the reference
frequency fr down to the phase detector
comparison frequency fc.
The output frequency of the 6-bit R Counter is
related to the reference frequency by the following
equation:
fc = fr / (R + 1)
where 0 ≤ R ≤ 63
(5)
Note that programming R with “0” will pass the
reference frequency (fr) directly to the phase
detector.
Register Programming
Serial Interface Mode
When the loop is locked, Fin is related to the
reference frequency (fr) by the following equation:
Fin = [10 x (M + 1) + A + K/218] x (fr / (R+1))
where A ≤ M + 1, 1 ≤ M ≤ 511
In this mode, the prescaler and A counter are
powered down, and the input VCO frequency is
divided by the M counter directly. The following
equation relates Fin to the reference frequency fr:
(3)
A consequence of the upper limit on A is that Fin
must be greater than or equal to 90 x (fr / (R+1)) to
obtain contiguous channels. The A counter can
accept values as high as 15, but in typical
operation it will cycle from 0 to 9 between
increments in M.
Programming the M counter with the minimum
allowed value of “1” will result in a minimum M
counter divide ratio of “2”.
While the E_WR input is “low” and the S_WR
input is “low”, serial input data (Sdata input), B0 to
B20, are clocked serially into the primary register
on the rising edge of Sclk, MSB (B0) first. The LSB
is used as address bit. When “0”, the contents
from the primary register are transferred into the
secondary register on the rising edge of either
S_WR according to the timing diagrams shown in
Figure 4. When “1”, data is transferred to the
auxiliary register according to the same timing
diagram. The secondary register is used to
program the various counters, while the auxiliary
register is used to program the DSM.
Data are transferred to the counters as shown in
Table 8 on page 10.
Prescaler Bypass Mode (*)
Setting the frequency control register bit Pre_en
“high” allows Fin to bypass the ÷10/11 prescaler.

Direct Interface Mode
While the E_WR input is “high” and the S_WR input is “low”, serial input data (Sdata input), B0 to
B7, are clocked serially into the enhancement register on the rising edge of Sclk, MSB (B0) first. The
enhancement register is double buffered to prevent inadvertent control changes during serial
loading, with buffer capture of the serially entered
data performed on the falling edge of E_WR according to the timing diagram shown in Figure 4.
After the falling edge of E_WR, the data provide
control bits as shown in Table 9 on page 10 will
have their bit functionality enabled by asserting
the Enh input “low”.
Direct Interface Mode is selected by setting the
“Direct” input “high”.
Counter control bits are set directly at the pins as
shown in Table 7 and Table 8.

Product Specification
Phase Detector and Charge Pump
The phase detector is triggered by rising edges
from the main Counter (fp) and the reference
counter (fc). It has two outputs, namely PD_U,
and PD_D. If the divided VCO leads the divided
reference in phase or frequency (fp leads fc),
PD_D pulses “low”. If the divided reference leads
the divided VCO in phase or frequency (fc leads
fp), PD_U pulses “low”. The width of either pulse
is directly proportional to phase offset between the
two input signals, fp and fc.
For the UP and DOWN mode, PD_U and PD_D
drive an active loop filter which controls the VCO
tune voltage. The phase detector gain is equal to
VDD / 2 п.
PD_U pulses cause an increase in VCO frequency and PD_D pulses cause a decrease in
VCO frequency, for a positive Kv VCO.
For the charge pump mode, the phase detector
outputs are used internally to drive a tri-state
charge pump. However, the PD_U, and PD_D output pins will be drive statically to GND. The
charge pump will drive a fixed 2 mA of current.
A lock detect output, LD is also provided, via the
pin Cext. Cext is the logical “NAND” of PD_U and
PD_D waveforms, which is driven through a series
2 kΩ resistor. Connecting Cext to an external
shunt capacitor provides low pass filtering of this
signal. Cext also drives the input of an internal inverting comparator with an open drain output.
Thus LD is an “AND” function of PD_U and PD_D.
