Product Specification
PE3239
Product Description
Peregrine’s PE3239 is a high performance integer-N PLL
capable of frequency synthesis up to 2.2 GHz. The
superior phase noise performance of the PE3239 is ideal
for applications such as wireless local loop basestations,
LMDS systems and other demanding terrestrial systems.
The PE3239 features a 10/11 dual modulus prescaler,
counters, phase detector and a charge pump 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 PE3239 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.

Same as pin 1.
Prescaler input from the VCO. Max frequency input is 2.2 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

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.
