Frequently Asked Questions
What supply voltages does SG-210STF 25.0000MS3 support, and how does this benefit mixed-voltage PCB designs?
The SG-210STF 25.0000MS3 operates at 1.8 V, 2.5 V, or 3.3 V supply voltage, making it compatible with a wide range of modern SoC and FPGA power domains without needing separate oscillator part numbers for each voltage. This multi-voltage flexibility reduces BOM variants, simplifies procurement, and allows the same oscillator to clock both a 1.8 V IoT SoC and a 3.3 V peripheral interface on the same board.
How does the ±25 ppm frequency accuracy of SG-210STF 25.0000MS3 affect Ethernet and USB timing requirements?
At ±25 ppm, the SG-210STF 25.0000MS3 meets the ±50 ppm total system accuracy budget required by Fast Ethernet (100BASE-T) and USB 2.0 full-speed specifications with margin to spare. For 25 MHz Ethernet PHY clocking, this tolerance ensures the recovered clock stays within the ±100 ppm jitter budget even after aging drift over a 10-year product lifetime.
For an FPGA design running at 25 MHz, what advantages does a 4-pin SMD oscillator offer over a crystal and oscillator circuit?
A 4-pin SMD oscillator like the SG-210STF 25.0000MS3 eliminates the need for external load capacitors (typically 2 x 18 pF), a Pierce oscillator amplifier, and matching resistors, saving 4 to 6 passive components and approximately 10 to 20 square millimeters of PCB area. The integrated oscillator also starts up in under 5 milliseconds, faster than most discrete crystal circuits that require 10 to 50 milliseconds for stable oscillation.
How does the 55% duty cycle output of SG-210STF 25.0000MS3 compare to standard CMOS clock requirements?
Most digital ICs including microcontrollers, FPGAs, and DDR memory controllers specify a clock duty cycle tolerance of 45% to 55%, making the 55% output of SG-210STF 25.0000MS3 compliant with virtually all standard CMOS clock inputs. At 25 MHz, a 55% duty cycle corresponds to a high pulse width of 22 nanoseconds and a low pulse width of 18 nanoseconds, well within setup and hold timing margins for most synchronous digital logic.
