Low Power Wideband Fractional
RF Synthesizer / PLL
8V97051
Datasheet
General Description
The 8V97051 is a high performance Wideband RF Synthesizer / PLL
optimized for use as the local oscillator (LO) in Multi-Carrier,
Multi-mode FDD & TDD Base Station radio card. It is offered in a
compact 5x5, 32-VFQFN package.
The 8V97051 Wideband RF Synthesizer / PLL offers a default
Fractional Mode with the option to use it with an Integer mode. It
requires an external loop filter.
The 8V97051 with 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 a SPI command
or mute pin.
The operation of the 8V97051 is controlled by writing to registers
through a 3-wire SPI interface. The 8V97051 also has an additional
option that allows users to read back values from registers by
configuring the MUX_OUT pin as a SDO for the SPI interface. The
SPI interface is compatible with 1.8V logic and tolerant to 3.3V.
In multi-service base stations, very low noise oscillators are required
to generate a large variety of frequencies to the mixers while
maintaining excellent phase noise performance and low power. The
8V97051 offers a large tuning range capable of providing multi-band
local oscillator (LO) frequency synthesis in multi-mode base stations,
thus limiting the use of multiple narrow band RF Synthesizers and
reducing the BOM complexity and cost. The device can operate over
-40°C to +85°C industrial temperature range.
