The LMX2695-SEP is a high performance wideband phase-locked loop (PLL) with integrated voltage controlled oscillator (VCO) that can output any frequency from 5MHz to 30GHz. 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 LMX2695-SEP 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.
