PRODUCT SPECIFICATION
PE3340
Product Description
Peregrine’s PE3340 is a high performance integer-N PLL
capable of frequency synthesis up to 3.0 GHz. The
superior phase noise performance of the PE3340 makes
it ideal for applications such as wireless local loop
basestations, LMDS systems and other demanding
terrestrial systems.
The PE3340 features a 10/11 dual modulus prescaler,
counters and a phase comparator as shown in Figure 1.
Counter values are programmable through a three wire
serial interface.
Fabricated in Peregrine’s patented UTSi® (Ultra Thin
Silicon) CMOS technology, the PE3340 offers excellent
RF performance with the economy and integration of
conventional CMOS.

Description
Power supply input. Input may range from 2.85 V to 3.15 V. Bypassing required.
Enhancement mode. When asserted low (“0”), enhancement register bits are functional. Internal 70 k
Ω
pull-up
resistor.
Serial load enable input. While S_WR is “low”, Sdata can be serially clocked. Primary register data are
transferred to the secondary register on S_WR rising edge.
Binary serial data input. Input data entered MSB first.
Serial clock input. Sdata is clocked serially into the 20-bit primary register (E_WR “low”) or the 8-bit
enhancement register (E_WR “high”) on the rising edge of Sclk.
Ground.

Selects contents of primary register (FSELS=1) or secondary register (FSELS=0) for programming of internal
counters. Internal 70 k

Enhancement register write enable. While E_WR is “high”, Sdata can be serially clocked into the enhancement
register on the rising edge of Sclk. Internal 70 k
Ω
pull-down resistor.
Same as pin 1.
Prescaler input from the VCO. Max frequency input is 3.0 GHz.
Prescaler complementary input. A bypass capacitor should be placed as close as possible to this pin and be
connected in series with a 50
Ω
resistor to the ground plane.
Ground.
Output

Output
(Note 1)
Logical “NAND” of PD_U and PD_D terminated through an on chip, 2 k
Ω
series resistor. Connecting Cext to an
external capacitor will low pass filter the input to the inverting amplifier used for driving LD.
Lock detect is an open drain logical inversion of CEXT. When the loop is in lock, LD is high impedance,
otherwise LD is a logic low (“0”).
Data out function, Dout, enabled in enhancement mode.
Same as pin 1.

When handling this UTSi 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
rating specified in Table 4.
Latch-Up Avoidance
Unlike conventional CMOS devices, UTSi CMOS
devices are immune to latch-up.

fclk is verified during the functional pattern test. Serial programming sections of the functional pattern are clocked at 10 MHz to verify fclk
specification.
CMOS logic levels can be used to drive reference input if DC coupled. Voltage input needs to be a minimum of 0.5 Vp-p. For optimum phase
noise performance, the reference input falling edge rate should be faster than 80mV/ns.
Parameter is guaranteed through characterization only and is not tested.
