7V-14.7456MAAV-T

Crystals Overview

The 7V-14.7456MAAV-T is a fundamental mode quartz crystal resonator manufactured by TXC Corporation, designed for surface-mount applications. It operates at a nominal frequency of 14.7456 MHz with a frequency tolerance and stability of ±30 ppm. The component features an 8 pF load capacitance and a maximum equivalent series resistance (ESR) of 60 Ohms. It is housed in a compact 4-SMD, No Lead package measuring 3.2 mm x 2.5 mm with a maximum height of 0.90 mm. The device supports operation within a temperature range of -20°C to +70°C and utilizes a base harmonic working mode.

Crystals Feature Summary

• Fundamental mode quartz crystal resonator providing stable frequency generation
• Compact 4-SMD no-lead surface-mount package for automated assembly
• Designed for high-frequency timing applications requiring precise clock signals

Crystals Applications

• Digital signal processing circuits
• Communication equipment clock sources
• Microcontroller system oscillators

Crystals Procurement Notes

Verify the specific load capacitance requirement against the target circuit design, as this variant specifies 8 pF rather than the more common 12 pF. Confirm that the operating temperature range of -20°C to +70°C aligns with the environmental conditions of the end application. Ensure the PCB footprint matches the 3.2 mm x 2.5 mm SMD dimensions to guarantee proper solder joint formation and mechanical reliability during reflow processes.

Crystals Selection Notes

Select this component when a small form factor is required alongside standard commercial temperature ranges. The 14.7456 MHz frequency is suitable for video and data transmission standards. Compare the 8 pF load capacitance against existing designs; if the circuit requires 12 pF, consider the 7V-14.7456MAAE-T instead. Evaluate the ESR limit of 60 Ohms to ensure compatibility with the oscillator circuit's drive level constraints.

Crystals Part Context

This part belongs to the 7V series of ceramic crystals from TXC Corporation, which are characterized by their small size and low profile. The series is engineered for consumer electronics and portable devices where space conservation is critical. Unlike larger through-hole crystals, these SMD components facilitate high-volume manufacturing processes and reduce overall board real estate requirements.

Crystals Replacement Considerations

The 7V-14.7456MAAE-T serves as a direct functional substitute if the application can accommodate a 12 pF load capacitance instead of 8 pF. Both parts share identical frequency, tolerance, package dimensions, and temperature ratings. Verify that the oscillator circuit impedance matches the ESR specifications of the replacement unit to prevent startup failures or frequency drift issues.
