MULTI-BAND RF FREQUENCY SYNTHESIZER WITH

INTEGRATED VCOS

DATASHEET

1 Features

Figure 1. Package

■ Integer-N Frequency Synthesizer

■ Dual differential integrated VCOs with

automatic center frequency calibration:

– Direct Output:

3280 – 3900 MHz

3800 – 4400 MHz

VFQFPN28

Package

VFQFPN28

– Internal divider by 4:

820 – 975 MHz

VFQFPN28 in Tape & Reel

950 – 1100 MHz

■ Fast lock time: 150µs

tors (VCOs).

■ Dual modulus prescaler (64/65) and 2

programmable counters to achieve a feedback

division ratio from 4096 to 32767.

Showing high performance, high integration, low

power, and multi-band performances, STW81100

is a low cost one chip alternative to discrete PLL

and VCOs solutions.

■ Programmable reference frequency divider (9

bits)

STW81100 includes an Integer-N frequency syn-

thesizer and two fully integrated VCOs featuring

low phase noise performance and a noise floor of

-153dBc/Hz. The combination of wide frequency

range VCOs (thanks to center-frequency calibra-

tion over 32 sub-bands) and multiple output op-

tions (direct output, divided by 2 or divided by 4)

allows to cover the 820MHz-1100MHz, the

1640MHz-2200MHz and the 3280MHz-4400MHz

bands.

■ Phase frequency comparator and charge pump

■ Programmable charge pump current

■ Digital Lock Detector

■ I²C bus interface with 3 bit programmable

address (1100A₂A₁A₀)

■ 3.3V Power Supply

■ Power down mode

■ Small size exposed pad VFQFPN28 package

The STW81100 is designed with STMicroelectron-

ics advanced 0.35µm SiGe process.

5x5x1.0mm

■ Process: BICMOS 0.35µm SiGe
