Overview
Description
The 8V97053L 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 8V97053L wideband RF synthesizer/PLL offers a default Fractional mode with the option for an Integer mode. It requires an external loop filter.
The 8V97053L 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.
Features
- 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
- Integrated high-performance low dropout regulators (LDOs) for excellent power supply noise rejection
- Programmable output power level: -4dBm to +5dBm (up to +7 when using the extended registers)
- Mute function
- Ultra-low phase noise (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
