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.
