  • 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 625MHz-762.5MHz, the 1087.5MHz-1525MHz, the 2175MHz-3050MHz and the 4350MHz-5000MHz bands.
    The STW81103 is designed with STMicroelectronics advanced 0.35µm 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 (fast mode) with 3 bit programmable address (1100A2A1A0)
    • Small size exposed pad VFQFPN28 package 5mm x 5mm x 1.0mm
    • Power down mode (hardware and software)
    • 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).
