Reference Oscillator for DDS

RCLN1000C – 1GHz Low Phase Noise Reference Oscillator -136 dBc/Hz @ 10kHz RCLN1000C for AD9910 AD9912 Units

 

The RCLN1000C Oscillator is built on a VCXO and a high-speed comparator

It generates clean rectangular CMOS signal

This approach enables precise odd-order frequency multiplication

It is implemented in this design by a factor of 5 without introducing additional phase noise

To further improve frequency accuracy the oscillator incorporates a Phase-Locked Loop (PLL)

with a Temperature-Compensated Crystal Oscillator (TCXO) as the reference

It ensuring outstanding stability and reliability across a wide temperature range
