■ Excellent integrated phase noise

■ Fast lock time: 150µs

Applications

■ 2.5G and 3G Cellular Infrastructure Equipment

■ CATV Equipment

■ Instrumentation and Test Equipment

■ Other Wireless Communication Systems

Description

■ Dual modulus programmable prescaler (16/17

or 19/20)

The STMicroelectronics STW81102 is an

integrated RF synthesizer with voltage controlled

oscillators (VCOs). Showing high performance,

high integration, low power, and multi-band

performances, STW81102 is a low cost one chip

alternative to discrete PLL and VCOs solutions.

■ 2 programmable counters to achieve a

feedback division ratio from 256 to 65551

(prescaler 16/17) and from 361 to 77836

(prescaler 19/20).

■ Programmable reference frequency divider (10

bits)

STW81102 includes an Integer-N frequency

synthesizer and two fully integrated VCOs

featuring low phase noise performance and a

noise floor of -155dBc/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 from 750MHz to

905MHz and 1000MHz to 1162.5MHz, from

1500MHz to 1810MHz and 2000MHz to

2325MHz, from 3000MHz to 3620MHz and

4000MHz to 4650MHz bands.

■ Phase frequency comparator and charge pump

■ Programmable charge pump current

■ Digital Lock Detector

■ 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 STW81102 is designed with

STMicroelectronics advanced 0.35µm SiGe

process.
