Frequently Asked Questions
What output frequency and fall-time performance does VCC1-B3F-40M0000000 deliver for FPGA clock input?
The VCC1-B3F-40M0000000 provides a nominal 40 MHz clock output with a maximum fall time of 4 ns, which comfortably meets setup and hold requirements for most FPGA global clock inputs. This combination of precise frequency and fast edge speed ensures reliable clocking in high-speed digital logic designs operating at 40 MHz or its sub-harmonics.
How does the tri-state enable feature of VCC1-B3F-40M0000000 support low-power embedded system design?
The tri-state enable/disable pin on VCC1-B3F-40M0000000 allows the 40 MHz clock output to be placed in a high-impedance state, cutting dynamic power dissipation when the downstream logic is not active. This feature is valuable in battery-powered IoT nodes and sleep-mode designs where clock gating at the oscillator level reduces system current by eliminating switching losses across multiple clock-driven circuits.
What board footprint does the LDFN-4 package of VCC1-B3F-40M0000000 require and how does it compare to standard oscillator packages?
The LDFN-4 package used by VCC1-B3F-40M0000000 is a leadless surface-mount package typically measuring about 2 mm × 2 mm, significantly smaller than a traditional 4-pad SMD oscillator in a 5 mm × 3.2 mm footprint. This compact size reduces PCB area consumption by roughly 75%, making it an attractive choice for miniaturized designs such as wearables or compact industrial modules.
