3 Description
The LMX2592 device is a low-noise, wideband RF
PLL with integrated VCO that supports a frequency
range from 20 MHz to 9.8 GHz. The device supports
both fractional-N and integer-N modes, with a 32-bit
fractional divider allowing fine frequency selection.
Integrated noise of 49 fs for 6-GHz output makes it
an ideal low-noise source. Combining best-in-class
PLL and integrated VCO noise with integrated LDOs,
this device removes the need for multiple discrete
devices in high performance systems.
The device accepts input frequencies up to 1.4 GHz,
which combined with frequency dividers and
programmable low noise multiplier allows flexible
frequency planning. The additional programmable
low-noise multiplier lets users mitigate the impact of
integer boundary spurs. In Fractional-N mode, the
device can adjust the output phase by a 32-bit
resolution. For applications that need fast frequency
changes, the device supports a fast calibration option
which takes less than 25 µs.
This performance is achieved by using single 3.3-V
supply. It supports 2 flexible differential outputs that
can be configured as single-ended outputs as well.
Users can choose to program one output from the
VCO (or doubler) and the second from the channel
divider. When not being used, each output can be
muted separately.
