Description

The STMicroelectronics STW81103 is an integrated RF synthesizer with voltage controlled oscillators (VCOs). Showing high performance, high integration, low power, and multi-band performances, STW81103 is a low cost one chip alternative to discrete PLL and VCOs solutions.

STW81103 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 the 625 MHz-762.5 MHz, the 1087.5 MHz-1525 MHz, the 2175 MHz-3050 MHz and the 4350 MHz-5000 MHz bands.

The STW81103 is designed with STMicroelectronics advanced 0.35 µm SiGe process.

Features

■ Integer-N frequency synthesizer

■ Dual differential integrated VCOs with automatic center frequency calibration:

– 2500 - 3050 MHz (direct output)

– 4350 - 5000 MHz (direct output)

– 1250 - 1525 MHz (internal divider by 2)

– 2175 - 2500 MHz (internal divider by 2)

– 625 - 762.5 MHz (internal divider by 4)

– 1087.5 - 1250 MHz (internal divider by 4)

■ Excellent integrated phase noise

■ Fast lock time: 150µs

■ Dual modulus programmable prescaler (16/17 or 19/20)

■ 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)

■ Phase frequency comparator and charge pump

■ Programmable charge pump current

■ Digital lock detector

■ Dual digital bus interface: SPI and I2C bus (fast mode) with 3 bit programmable address (1100A2A1A0)
