7M-19.200MEEQ-T

Crystals Overview

The 7M-19.200MEEQ-T is a quartz crystal resonator manufactured by TXC Corporation, operating at a fundamental frequency of 19.2 MHz. It features a load capacitance of 10 pF and maintains a frequency tolerance and stability of ±10 ppm. The component utilizes a 4-SMD, no lead package with dimensions of 3.2 mm in length, 2.5 mm in width, and a maximum height of 0.7 mm. It exhibits an equivalent series resistance (ESR) of 50 Ohms and supports a drive level of 100 uW. The device is rated for operation within a temperature range of -20°C to +70°C.

Crystals Feature Summary

• Provides precise timing signals through fundamental mode oscillation at 19.2 MHz.
• Ensures stable frequency performance with ±10 ppm tolerance across the specified industrial temperature range.
• Designed for surface-mount assembly using a compact 4-SMD footprint.

Crystals Applications

• Clock generation for microcontrollers and digital logic circuits
• Timing references for communication interfaces such as UART or SPI
• Frequency control in consumer electronic devices requiring standard clock rates

Crystals Procurement Notes

Verify that the target circuit design accommodates the specific 10 pF load capacitance requirement to ensure accurate frequency output. Confirm that the PCB layout matches the 3.2 mm x 2.5 mm SMD footprint dimensions. Ensure the operating environment remains within the -20°C to +70°C range to maintain the specified ±10 ppm stability. Check datasheet specifications for ESR limits relative to the oscillator circuit impedance.

Crystals Selection Notes

Select this component when a fundamental mode crystal is required for 19.2 MHz applications with moderate stability needs. Compare against the 8Z series for smaller footprints or the 7V series for wider temperature ranges if environmental conditions exceed the -20°C to +70°C limit. Consider the 50 Ohm ESR value when designing the oscillator feedback network to ensure reliable startup.

Crystals Part Context

This part belongs to the 7M series of high-accuracy MHz crystals from TXC Corporation. The series is characterized by small form factors suitable for space-constrained portable electronics. It serves as a passive frequency-determining element, distinct from active oscillators like the 7L series, requiring an external oscillator circuit to generate a square wave signal.

Crystals Replacement Considerations

The 7M-19.200MEEQ-T may be substituted with other 19.2 MHz crystals sharing identical 10 pF load capacitance and ±10 ppm tolerance. Verify mechanical compatibility with the 3.2x2.5mm package and ensure the replacement part supports the same 100 uW drive level and 50 Ohm ESR specifications.
