  • 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 VCO solutions.

    The STW81101 includes an integer-N frequency synthesizer and two fully integrated VCOs featuring low phase-noise performance and a noise floor of -155 dBc/Hz. The combination of wide frequency range VCOs (using center-frequency calibration over 32 sub-bands) and multiple output options (direct output, divided by 2, or divided by 4) allows coverage of the 825 MHz-1100 MHz, 1650 MHz-2200 MHz and 3300 MHz-4400 MHz bands.
    The STW81101 is designed with STMicroelectronics advanced 0.35 µm SiGe process.

    主要特性

    • Digital Lock Detector
    • Programmable charge pump current
    • 3.3V Power Supply
    • Dual Digital Bus Interface: SPI and I2C bus with 3 bit programmable address (1100A2A1A0)
    • Small size exposed pad VFQFPN28 package 5x5x1.0mm
    • Power down mode (HW and SW)
    • Process: BICMOS 0.35μm SiGe
    • Programmable reference frequency divider (10 bits)
    • 2 programmable counters to achieve a feedback division ratio from 256 to 65551 (prescaler 16/17) and from 361 to 77836 (prescaler 19/20).
    • Integer-N Frequency Synthesizer
    • Excellent integrated phase noise
    • Dual differential integrated VCOs with automatic center frequency calibration:\t\t3300 - 3900 MHz (Direct output)\t\t3800 - 4400 MHz (Direct output)\t\t1650 - 1950 MHz (Internal divider by 2)\t\t1900 - 2200 MHz (Internal divider by 2)\t\t825 - 975 MHz (Internal divider by 4)\t\t950 - 1100 MHz (Internal divider by 4)\t\t
    • Dual modulus programmable prescaler (16/17 or 19/20)
    • Phase frequency comparator and charge pump
    • Fast lock time: 150μs
