描述

The 8V97053 is a high-performance GSM1800 grade wideband RF synthesizer/PLL optimized for use as the local oscillator (LO) in multi-carrier, multi-mode FDD and TDD base station radio cards. It is offered in a compact 5mm x 5mm, 32-VFQFN package.

The 8V97053 Wideband RF synthesizer/PLL offers a default fractional mode with the option for an integer mode. It requires an external loop filter.

The 8V97053 has an integrated voltage-controlled oscillator (VCO), supports output frequencies from 34.375MHz to 4400MHz, and maintains superior phase noise and spurious performance.

RF_OUT[A:B] output drivers have independently programmable output power ranging from –4dBm to +7dBm. The RF_OUT outputs can be muted. The mute function is accessible via an SPI command or mute pin.

特性

  • Dual differential outputs
  • Output frequency range: 34.375MHz to 4400MHz (continuous range)
  • RF output divided by 1, 2, 4, 8, 16, 32, 64
  • Open drain outputs (see output distribution section in the datasheet)
  • Fractional-N feedback divider (also supports Integer-N mode)
  • 16-bit integer and 12-bit fractional
    (16-bit fractional when using the extended registers)
  • 3- or 4-wire SPI interface (compatible with 3.3V and 1.8V)
  • Single 3.3V supply
  • Logic compatibility: 1.8V
  • Programmable output power level: -4dBm to +5dBm
    (up to +7 when using the extended registers)
  • Mute function
  • Ultra-low PN (typical phase noise for 1.65GHz LO: -142.21dBc/Hz at 1MHz Offset)
  • Lock detect indicators
  • Input reference frequency: 5MHz to 310MHz
  • 32-Lead, 5mm x 5mm VFQFN package
  • Automatic VCO band selection (AutoCal feature)
  • -40 °C to +85 °C ambient operating temperature
  • Supports +105 °C case temperature
  • Lead-free (RoHS 6) packaging​
