The NBXDDB016/NBXDDA016 dual frequency crystal oscillator (XO) is designed to meet today’s requirements for 3.3 V CML clock generation applications. The device uses a high Q fundamental crystal and Phase Lock Loop (PLL) multiplier to provide selectable 133.33 MHz or 137.93 MHz, ultra low jitter and phase noise CML differential output.
This device is a member of ON Semiconductor’s PureEdge clock family that provides accurate and precision clock solutions.
Available in 5 mm x 7 mm SMD (CLCC) package on 16 mm tape and reel in quantities of 1,000. Frequency stability options available as either 50 PPM NBXDDB016 or 20 PPM NBXDDA016.
