What are the key features of X14M745600L225?

14.7456 MHz frequency — a standard UART baud rate crystal for zero-error serial communication at 9600 to 921600 bps
30 pF load capacitance and 50 ppm tolerance for compatibility with common microcontroller oscillator circuits
100 µW maximum drive level protects crystal integrity across the full operating life
Resistance-welded hermetic package with ±5 ppm/first year aging ensures long-term frequency stability

What is X14M745600L225 used for?

The X14M745600L225 at 14.7456 MHz is the classic frequency reference for UART-based serial communication circuits in embedded systems, as it divides evenly to standard baud rates from 9600 bps to 921600 bps without frequency error. It is widely used in microcontroller development boards, serial data loggers, RS-232/RS-485 interface modules, and Ethernet-to-serial bridge devices. The through-hole package suits prototyping environments and legacy hardware designs where SMD mounting is not required.

Frequently Asked Questions

Why is 14.7456 MHz chosen for UART timing, and how does X14M745600L225 achieve exact baud rates?

14.7456 MHz divides exactly by integer factors to produce standard UART baud rates: 14745600 / 1536 = 9600 bps, / 192 = 76800 bps, / 16 = 921600 bps, all with 0% error. The X14M745600L225 delivers this frequency at 30 pF load capacitance with ±50 ppm tolerance, meaning the actual baud rate error is less than ±0.005% — well within the ±2% window UART receivers tolerate — making it the preferred crystal for serial communication ASICs and microcontrollers.

What external load capacitors are needed to match the 30 pF specification of X14M745600L225 in a Pierce oscillator circuit?

For a Pierce oscillator with the X14M745600L225 specified at 30 pF load capacitance, two external capacitors of approximately 56 pF each connected from each crystal pin to ground are typically needed. The effective load seen by the crystal is (C1 × C2) / (C1 + C2) plus the PCB stray capacitance (typically 3–5 pF). With 56 pF capacitors and 4 pF stray, the load is 56/2 + 4 = 32 pF, closely matching the 30 pF specification for accurate frequency.

How does the 5 ppm/first year aging rate of X14M745600L225 affect long-deployed serial communication equipment?

The ±5 ppm/first year aging of the X14M745600L225 means that over the first year of operation, the 14.7456 MHz frequency can drift up to 73.7 Hz. For UART communication at 115200 bps, this equates to a baud rate error of approximately 0.0005%, far below the ±2% tolerance of standard UART receivers. Even after 10 years of cumulative aging (estimated ≤20 ppm total), the baud rate error remains negligible for all standard serial data rates up to 921600 bps.
