/137.93 MHz Dual
Frequency CML Clock
Oscillator
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 PureEdget 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.
Features
• CML Differential Output
• Uses High Q Fundamental Mode Crystal and PLL Multiplier
• Ultra Low Jitter and Phase Noise − 0.4 ps (12 kHz − 20 MHz)
• Selectable Output Frequency − 133.33 MHz (default)/137.93 MHz
• Hermetically Sealed Ceramic SMD Package
• RoHS Compliant
• Operating Range 3.3 V ±10%
• Total Frequency Stability − ±20 PPM or ±50 PPM
Applications
• High−End Servers
• Basestation
• General Purpose Clock Generation and Margining
