Key Features

  • 25 MHz CMOS output oscillator with ±25 ppm frequency stability for precision timing applications
  • Multi-voltage supply compatibility: 1.8 V, 2.5 V, and 3.3 V in a single part number for design flexibility
  • 15 pF load capacitance and 55% duty cycle CMOS output for clean clock signal integrity
  • 4-pin SMD package enables compact PCB footprint and automated tape-and-reel SMT assembly
  • Factory-trimmed frequency eliminates the need for external load capacitors or tuning components

Applications

The SG-210STF 25.0000MS3 is ideal as a system clock source for microcontrollers, FPGAs, and Ethernet PHY devices in embedded computing, IoT sensor nodes, and industrial control systems where 25 MHz is a standard clock frequency. Its 1.8 V to 3.3 V supply range allows direct integration with modern low-power SoCs operating on single-cell LiPo batteries or regulated 3.3 V rails. The compact 4-pin SMD package suits high-density PCB designs in wearable devices, wireless modules, and portable data loggers requiring accurate ±25 ppm timing.

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.
