STW81103AT Product details

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)
■ 3.3 V power supply
■ Power down mode (hardware and software)
■ Small size exposed pad VFQFPN28 package 5 mm x 5 mm x 1.0 mm
■ Process: BICMOS 0.35 µm SiGe

Applications
■ 2.5G and 3G Cellular infrastructure equipment
■ CATV equipment
■ Instrumentation and test equipment
■ Other wireless communication systems
