How FCom Develops the Timing Solution

The recommendation starts with the complete subsystem and design requirements rather than selecting a part from frequency alone.

01

Review the System

Review the application, target chipset, interfaces, operating environment and key design requirements.

02

Map the Clock Nodes

Identify processor, PHY, FPGA, sensor, RF and RTC clock requirements across the subsystem.

0103

Match the Timing Devices

Select the appropriate crystal, XO, TCXO or differential oscillator for each required clock function.

0204

Define the Validation Path

Confirm prototype samples, technical verification, qualification requirements and production considerations.

Support Beyond the Initial Product Recommendation

FCom supports architecture review, replacement evaluation, customization and project qualification based on the actual application requirements.

SYS

System-Level Clock Review

Review clock functions, device interfaces and performance priorities across the complete subsystem.

ALT

Replacement Matching

Compare an existing part against frequency, package, output, supply, stability, temperature and key electrical requirements.

ENG

Custom Engineering

Review non-standard frequency, stability, output, package or application-specific performance requirements.

QLT

Qualification Planning

Coordinate sample requirements, technical documentation and project-specific qualification considerations.

Have an existing crystal, oscillator or competitor part number?

Send the original part number or datasheet. FCom can review the specification, package and electrical requirements to support replacement evaluation.
