Product Specification
PE3341
Product Description
The PE3341 is a high performance integer-N PLL with
embedded EEPROM capable of frequency synthesis up to
2700 MHz with a speed-grade option to 3000 MHz. The
EEPROM allows designers to permanently store control bits,
allowing easy configuration of self-starting synthesizers. The
superior phase noise performance of the PE3341 is ideal for
applications such as sonet, wireless base stations, fixed
wireless, and RF instrumentation systems.
The PE3341 features a ÷10/11 dual modulus prescaler,
counters, a phase comparator, and a charge pump as shown in
Figure 1. Counter values are programmable through a three-
wire serial interface.
The PE3341 UltraCMOS™ Phase Locked-Loop is
manufactured in Peregrine’s patented Ultra Thin Silicon
(UTSi®) CMOS process, offering excellent RF performance
with the economy and integration of conventional CMOS.

Description
Secondary Register WRITE input. Primary Register contents are copied to the Secondary Register on
S_WR rising edge. Also used to control Serial Port operation and EEPROM programming.
Binary serial data input. Input data entered LSB (B
0
) first.
Serial clock input. Data is clocked serially into the 20-bit Primary Register, the 20-bit EE Register, or
the 8-bit Enhancement Register on the rising edge of Clock. Also used to clock EE Register data out
Dout port.
Frequency Register selection control line. Internal 70 kW pull-down resistor.
Enhancement Register write enable. Also functions as a Serial Port control line. Internal 70 kW pull-
down resistor.
EEPROM erase/write programming voltage supply pin. Requires a 100pF bypass capacitor connected
to GND.
Power supply input. Input may range from 2.85 V to 3.15 V. Bypassing required.
Prescaler input from the VCO.
Prescaler complementary input. A series 50 W resistor and DC blocking capacitor should be placed as
close as possible to this pin and connected to the ground plane.
Logical “NAND” of PD_U and PD_D terminated through an on-chip, 2 kW series resistor. Connecting
C
EXT
to an external capacitor will low pass filter the input to the inverting amplifier used for driving LD.
Control line for Serial Data Port, Frequency Register selection, EE Register parallel loading, and
EEPROM programming. Internal 70 kW pull-down resistor.
Lock detect output, an open-drain logical inversion of C
EXT
. When the loop is in lock, LD is high
impedance; otherwise, LD is a logic LOW.
Data out function. Dout is defined with the Enhancement Register and enabled with ENH.
Same as pin 7.
Charge pump output. Sources current is when f
c
leads f
p
and sinks current when f
c
lags f
p
.
No connection.

pins 7, 14 and 19 are connected by diodes and must be supplied with the same positive voltage level.
2:
Ground connections are made through the exposed solder pad. The solder pad must be soldered to the ground plane for proper operation.

Exceeding absolute maximum ratings may cause
permanent damage. Operation should be
restricted to the limits in the Operating Ranges
table. Operation between operating range
maximum and absolute maximum for extended
periods may reduce reliability.
Note 1:
Periodically sampled, not 100% tested. Tested per MIL-
STD-883, M3015 C2
Electrostatic Discharge (ESD) Precautions
When handling this UltraCMOS™ device, observe
the same precautions that you would use with
other ESD-sensitive devices. Although this device
contains circuitry to protect it from damage due to
ESD, precautions should be taken to avoid
exceeding the specified rating in Table 4.
Latch-Up Avoidance
Unlike conventional CMOS devices, UltraCMOS™
devices are immune to latch-up.
