TS540T23CET

Crystals Overview

The TS540T23CET is a surface-mount crystal oscillator manufactured by CTS-Frequency Controls. It operates at a fundamental frequency of 54 MHz with a load capacitance of 20 pF. The component features a frequency stability of ±30 ppm and a frequency tolerance of ±20 ppm. It utilizes an HC-49/US-SM package, measuring 11.10 mm in length, 4.83 mm in width, and 4.30 mm in maximum seated height. The device supports third-overtone operation mode and exhibits an equivalent series resistance (ESR) of 80 Ohms. It functions within a temperature range of -20°C to +70°C.

Crystals Feature Summary

• Surface-mount design compatible with automated assembly processes

Crystals Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, as standard delivery may involve tape-and-reel formats. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Cross-reference the manufacturer part number with distributor catalogs to validate current availability and lead times against project schedules.

Crystals Selection Notes

Select this component when a 54 MHz surface-mount crystal with 20 pF load capacitance is required. Ensure the application circuit supports third-overtone operation modes. Verify that the PCB layout accommodates the HC-49/US-SM footprint dimensions. Consider the ±30 ppm stability requirement relative to system timing accuracy needs.

Crystals Part Context

This part belongs to the ATSMTS series of surface-mount crystals from CTS-Frequency Controls. It shares the HC-49/US-SM package style with other models in the family but differs in frequency and overtone specifications. The series provides standardized mounting options for high-reliability timing applications.
