Frequently Asked Questions
What output frequency and stability does the VCC1-B3D-125M000000 provide for network timing applications?
The VCC1-B3D-125M000000 delivers a nominal output frequency of 125 MHz with a frequency stability of ±50 ppm over the operating temperature range. This level of stability is well-suited for Ethernet PHY clocking and other networking applications where a consistent 125 MHz reference is needed without an external PLL.
How does the tri-state enable feature of VCC1-B3D-125M000000 support power management in a multi-clock design?
The tri-state enable/disable pin allows the designer to place the 125 MHz CMOS output in a high-impedance state, effectively disconnecting it from the clock bus without removing power from the oscillator. This is useful in multi-source clock topologies and standby modes, reducing dynamic power consumption and preventing bus contention in systems with 2 or more clock sources sharing a line.
What package and supply voltage does VCC1-B3D-125M000000 use, and how does that compare to through-hole oscillator alternatives?
The VCC1-B3D-125M000000 uses an LDFN-4 surface-mount package and operates at 3.3 V, offering a much smaller PCB footprint than 14-pin DIP through-hole oscillators. The 2 ns maximum fall time and surface-mount form factor make it compatible with automated pick-and-place assembly, reducing placement costs and supporting board densities required in compact networking hardware.
