3 Description
The LMX2624-SP is a high performance wideband
phase-locked loop (PLL) with integrated voltage
controlled oscillator (VCO) and voltage regulators that
can output any frequency from 5MHz and 28GHz.
The VCO on this device covers an entire octave so
the frequency coverage is complete down to 5MHz.
The high performance PLL with a figure of merit of
–236dBc/Hz and high phase detector frequency can
attain very low in-band noise and integrated jitter.
The LMX2624-SP allows users to synchronize the
output of multiple instances of the device. This
means that deterministic phase can be obtained
from a device in use cases including the one
with fractional engine or output divider enabled.
The device also adds support for either generating
or repeating SYSREF (compliant to JESD204B/C
standard), making the device designed for low-noise
clock source for high-speed data converters.
This device is fabricated in Texas Instruments'
advanced BiCMOS process and is available in a 64-
lead QFP plastic package.
