onsemi Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers NB3N49152MNTXG

The NB3N49152MNTXG is a voltage-controlled crystal oscillator (VCXO) designed for 3.3 V LVPECL clock generation applications. It operates within a frequency range of 60 MHz to 700 MHz, specifically configured for 491.52 MHz in this part number. The device features ultra-low jitter and phase noise, with a typical jitter of 0.5 ps across a frequency range of 12 kHz to 20 MHz. It has a pullable range of ±100 ppm and is housed in a compact 4 mm x 4 mm QFN-20 package. The NB3N49152MNTXG supports an ambient operating temperature range of -40°C to +85°C and is compliant with RoHS standards. It includes differential LVPECL outputs, with rise and fall times typically around 245 ps. The device requires an external high Q fundamental mode pullable crystal for operation and offers a control voltage input that adjusts the output frequency. This product is suitable for applications in networking, SONET, 10 Gigabit Ethernet, and broadcasting.
