STW81103AT
Multi-band RF frequency synthesizer with integrated VCOs, VFQFPN28, STM, RoHS


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 VCO solutions

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