PEREGRINE 9601-00

Product Specification
PE9601
2200 MHz UltraCMOS™ Integer-N PLL
for Rad Hard Applications
Product Description
Peregrine’s PE9601 is a high performance integer-N PLL
capable of frequency synthesis up to 2200 MHz. 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.
The PE9601 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.
The PE9601 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 UltraCMOS™ process
technology, the PE9601 offers excellent RF performance and
intrinsic radiation tolerance.

PE9601
Product Specification
Functional Description
The PE9601 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, which are implemented as a pulse width
modulated current by the charge pump. The
control logic includes a selectable chip interface.
Data can be written via serial bus, parallel bus, or
hardwired direct to the pins. There are also
various operational and test modes and lock
detect.

PE9601
Product Specification
Main Counter Chain
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:
fp = Fin / [10 x (M + 1) + A]
where A ≤ M + 1, M ¹ 0
(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, M ¹ 0
(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.
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 R > 0
(3)
Note that programming R equal to “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”).
Register Programming
Parallel Interface Mode
Parallel Interface Mode is selected by setting the
Bmode input “low” and the Smode input “low”.
Document No. 70-0025-05 │ www.psemi.com
Parallel input data, D[7:0], are 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
10. 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 6. Data are transferred to the
counters as shown in Table 7 on page 10.
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.
The FSELP input is synchronized with the loading of
the counters in order to minimize glitches in the
“ping-pong” case. Due to this attribute, applications
using a single register should use the secondary
register (i.e. tie FSELP “low”) to avoid problems with
the prescaler powering up in the disabled state.
Parallel input data, D[7:0], are latched into the
enhancement register on the rising edge of E_WR
according to the timing diagram shown in Figure 6.
This data provides control bits as shown in Table 8
on page 10 with bit functionality enabled by
asserting the Enh input “low”.
Direct Interface Mode
Direct Interface Mode is selected by setting the
Bmode input “high”.
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”)
Serial Interface Mode
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, are
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 and Figure 7. Data are transferred to the
counters as shown in Table 7 on page 10.

PE9601
Product Specification
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
7. After the falling edge of E_WR, the data
provide control bits as shown in Table 8 with bit
functionality enabled by asserting the Enh input
“low”.
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.
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.

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 and
PD_D results in a current sink, which decreases
VCO frequency.
A lock detect output, LD is also provided, via the
pin Cext. Cext is the logical “OR” of PD_U and
PD_D waveforms, which is driven through a series
2 k ohm 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 “NOR”
function of PD_U and PD_D.
