Description
The 8V97053 is a high-performance Wideband RF Synthesizer /
PLL optimized for use as the local oscillator (LO) in Multi-Carrier,
Multi-mode FDD, and TDD Base Station radio card. It is offered in
a compact 5  5, 32-VFQFPN.
The 8V97053 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 8V97053 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 8V97053 is controlled by writing to registers
through a 3-wire SPI interface. The 8V97053 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 is 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 8V97053 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.
