STW81101AT
Multi-band RF frequency synthesizer with integrated VCOs, VFQFPN28, STM, RoHS

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.

Features:

  • Integer-N Frequency Synthesizer
  • Dual differential integrated VCOs with automatic center frequency calibration: 3300 - 3900 MHz (Direct output) 3800 - 4400 MHz (Direct output) 1650 - 1950 MHz (Internal divider by 2) 1900 - 2200 MHz (Internal divider by 2) 825 - 975 MHz (Internal divider by 4) 950 - 1100 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 with 3 bit programmable address (1100A2A1A0)
  • 3.3V Power Supply
  • Power down mode (HW and SW)
  • Small size exposed pad VFQFPN28 package 5x5x1.0mm
  • Process: BICMOS 0.35µm SiGe
