STW81101

Multi-band RF frequency synthesizer with integrated VCOs

Preliminary Data

Feature summary

■ Integer-N Frequency Synthesizer

■ Dual differential integrated VCOs with

automatic center frequency calibration:

– 3300 - 3900 MHz (Direct output)

– 3800 - 4400 MHz (Direct output)

– 1650 - 1950 MHz (Internal divider by 2)

– 1900 - 2200 MHz (Internal divider by 2)

– 825 - 975 MHz (Internal divider by 4)

– 950 - 1100 MHz (Internal divider by 4)

■ Excellent integrated phase noise

■ Fast lock time: 150µs

VFQFPN28

Applications

■ 2.5G and 3G Cellular Infrastructure Equipment

■ CATV Equipment

■ Instrumentation and Test Equipment

■ Other Wireless Communication Systems

■ Dual modulus programmable prescaler (16/17

or 19/20)

Description

■ 2 programmable counters to achieve a

feedback division ratio from 256 to 65551

(prescaler 16/17) and from 361 to 77836

(prescaler 19/20).

The STMicroelectronics STW81101 is an

integrated RF synthesizer with voltage controlled

oscillators (VCOs). Showing high performance,

high integration, low power, and multi-band

performances, STW81101 is a low cost one chip

alternative to discrete PLL and VCOs solutions.

■ Programmable reference frequency divider (10

bits)

■ Phase frequency comparator and charge pump

■ Programmable charge pump current

■ Digital Lock Detector

STW81101 includes an Integer-N frequency

synthesizer and two fully integrated VCOs

featuring low phase noise performance and a

noise floor of -154dBc/Hz. The combination of

wide frequency range VCOs (thanks to center-

frequency calibration over 32 sub-bands) and

multiple output options (direct output, divided by 2

or divided by 4) allows to cover the 825MHz-

1100MHz, the 1650MHz-2200MHz and the

3300MHz-4400MHz bands.

■ Dual Digital Bus Interface: SPI and I C bus with

3 bit programmable address (1100A A A )

1 0

■ 3.3V Power Supply

■ Power down mode (HW and SW)

■ Small size exposed pad VFQFPN28 package

5x5x1.0mm

■ Process: BICMOS 0.35µm SiGe

The STW81101 is designed with

STMicroelectronics advanced 0.35µm SiGe

process.
