Product Specification
PE9701
3000 MHz UltraCMOS™ Integer-N PLL
Rad Hard for Space Applications
Product Description
Peregrine’s PE9701 is a high-performance integer-N PLL
capable of frequency synthesis up to 3.0 GHz. The device
is designed for superior phase noise performance while
providing an order of magnitude reduction in current
consumption, when compared with existing commercial
space PLLs.
Features
The PE9701 features a 10/11 dual modulus prescaler,
counters, and a phase comparator as shown in Figure 1.
Counter values are programmable through either a serial or
parallel interface and can also be directly hard wired.
• Serial, parallel or hardwired
• 3.0 GHz operation
• ÷10/11 dual modulus prescaler
• Internal phase detector with charge
pump
programmable
• Ultra-low phase noise
• SEU < 10-9 errors / bit-day
The PE9701 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. It is manufactured on Peregrine’s
UltraCMOS™ process, a patented variation of silicon-oninsulator (SOI) technology on a sapphire substrate, offering
excellent RF performance and intrinsic radiation tolerance.

Product Specification
Functional Description
The PE9701 consists of a prescaler, counters, a
phase detector, a charge pump, and control logic.
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 phase-frequency
detector generates up and down frequency control
signals. The control logic includes a selectable
chip interface. Data can be written via serial bus,
parallel bus, or hardwired directly to the pins.
There are also various operational and test modes
and a lock detect output.

Product Specification
Main Counter Chain
Reference Counter
Normal Operating Mode
The main counter chain divides the RF input
frequency, Fin, by an integer derived from the
user-defined values in the “M” and “A” counters. It
is composed of the 10/11 dual modulus prescaler,
modulus select logic, and 9-bit M counter. Setting
Pre_en “low” enables the 10/11 prescaler. Setting
Pre_en “high” allows Fin to bypass the prescaler
and powers down the prescaler.
The output from the main counter chain, fp, is
related to the VCO frequency, Fin, by the following
equation:
The reference counter chain divides the
reference frequency, fr, down to the phase
detector comparison frequency, fc.
fp = Fin / [10 x (M + 1) + A]
where A ≤ M + 1, 1 ≤ M ≤ 511
(1)
When the loop is locked, Fin is related to the
reference frequency, fr, by the following equation:
Fin = [10 x (M + 1) + A] x (fr / (R+1))
where A ≤ M + 1, 1 ≤ M ≤ 511
(2)
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. Programming the M
Counter with the minimum value of “1” will result in
a minimum M Counter divide ratio of “2”.
In Direct Interface Mode, main counter inputs M7
and M8 are internally forced low. In this mode, the
M value is limited to 1 ≤ M ≤ 127.
Prescaler Bypass Mode
Setting Pre_en “high” allows Fin to bypass and
power down the prescaler. In this mode, the
10/11 prescaler and A register are not active, and
the input VCO frequency is divided by the M
counter directly. The following equation relates Fin
to the reference frequency, fr:
Fin = (M + 1) x (fr / (R+1)) )
where 1 ≤ M ≤ 511
(3)
In Direct Interface Mode, main counter inputs M7
and M8 are internally forced low. In this mode, the
M value is limited to 1 ≤ M ≤ 127.
©2003-2006 Peregrine Semiconductor Corp. All rights reserved.
Page 8 of 13
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
(4)
Note that programming R with “0” will pass the
reference frequency, fr, directly to the phase
detector.
In Direct Interface Mode, R Counter inputs R4
and R5 are internally forced low (“0”). In this
mode, the R value is limited to 0 ≤ R ≤ 15.
Register Programming
Parallel Interface Mode
Parallel Interface Mode is selected by setting the
Bmode input “low” and the Smode input “low”.
Parallel input data, D[7:0], is latched in a parallel
fashion into one of three 8-bit primary register
sections on the rising edge of M1_WR, M2_WR,
or A_WR per the mapping shown in Table 7 on
page 9. The contents of the primary register are
transferred into a secondary register on the
rising edge of Hop_WR according to the timing
diagram shown in Figure 5. Data is transferred
to the counters as shown in Table 7 on page 9.
The secondary register acts as a buffer to allow
rapid changes to the VCO frequency. This
double buffering for “ping-pong” counter control
is programmed via the FSELP input. When
FSELP is “high”, the primary register contents
set the counter inputs. When FSELP is “low”,
the secondary register contents are utilized.
Parallel input data, D[7:0], is latched into the
enhancement register on the rising edge of
E_WR according to the timing diagram shown in
Figure 5. This data provides control bits as
shown in Table 8 on page 9 with bit functionality
enabled by asserting the Enh input “low”
Document No. 70-0035-02 │ UltraCMOS™ RFIC Solutions
PE9701
Product Specification
Serial Interface Mode
B7, is 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
6. After the falling edge of E_WR, the data
provides control bits as shown in Table 8 with bit
functionality enabled by asserting the Enh input
“low”.
Serial Interface Mode is selected by setting the
Bmode input “low” and the Smode input “high”.
While the E_WR input is “low” and the S_WR
input is “low”, serial input data (Sdata input), B0 to
B19, is clocked serially into the primary register on
the rising edge of Sclk, MSB (B0) first. The
contents from the primary register are transferred
into the secondary register on the rising edge of
either S_WR or Hop_WR according to the timing
diagram shown in Figure 6. Data is transferred to
the counters as shown in Table 7 on page 9.
Direct Interface Mode
Direct Interface Mode is selected by setting the
Bmode input “high”.
The double buffering provided by the primary and
secondary registers allows for “ping-pong” counter
control using the FSELS input. When FSELS is
“high”, the primary register contents set the
counter inputs.
When FSELS is “low”, the
secondary register contents are utilized.
Counter control bits are set directly at the pins as
shown in Table 7. In Direct Interface Mode, main
counter inputs M7 and M8, and R Counter inputs
R4 and R5 are internally forced low (“0”).
While the E_WR input is “high” and the S_WR
input is “low”, serial input data (Sdata input), B0 to

Phase Detector
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 “high”. If the divided reference leads
the divided VCO in phase or frequency (fr leads
fp), PD_U pulses “high”. The width of either pulse
is directly proportional to phase offset between the
two input signals, fp and fc.
The signals from the phase detector couple
directly to a charge pump. PD_U controls a
current source at pin CP with constant amplitude
and pulse duration approximately the same as
PD_U. PD_D similarly drives a current sink at

pin CP. The current pulses from pin CP are low
pass filtered externally and then connected to the
VCO tune voltage. PD_U pulses result in a
current source, which increases the VCO
frequency; PD_D pulses result in a current sink,
which decreases VCO frequency.
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
2k Ω resistor. Connecting Cext to an external
shunt capacitor provides integration. 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. See Figure 4 for a
schematic of this circuit.
