Low phase noise oscillators come in industry standard packages
Stephen LawElectronics clock low-phase noise oscillators
WüRTH ELEKTRONIK IQD brand IQXO-408 & IQXO-455 low phase noise oscillators are available in industry standard packages of 2.5 x 2.0mm and 3.2 x 2mm. The CMOS clock oscillators can perform with a close in phase noise as low as -113dBc/Hz @ 10Hz and far out phase noise as low as -175dBc/Hz @ 100kHz (3.3V, 20MHz, IQXO-408). Devices are available at either 1.8 V, 2.5 V or 3.3 V with a phase jitter down to 40 fs RMS (over 12 kHz to 5 MHz). Common applications include high data rate applications, IoT, 5G, PLL, frequency multiplier, clock recovery, gigabit Ethernet, fibre, studio grade and high-end consumer audio equipment.
