9B-54.000MAAJ-B

Crystals Overview

The FTS 9B-54.000MAAJ-B is a MHz crystal oscillator designed for precise frequency generation in electronic circuits. Operating at a nominal frequency of 54 MHz, this component provides stable clock signals essential for digital systems. It features a frequency stability and tolerance of ±30ppm, ensuring reliable performance under varying conditions. The unit utilizes an HC-49S package, offering a compact form factor suitable for surface mount or through-hole applications depending on specific board layouts. With an equivalent series resistance (ESR) of 60 Ohms and a load capacitance of 18 pF, it integrates seamlessly into standard oscillator designs requiring high accuracy and consistent timing references.

• Ensures timing accuracy with ±30ppm stability
• Utilizes HC-49S package for compact integration

Crystals Applications

• Digital clock signal generation
• Microcontroller system timing
• Communication interface synchronization

Crystals Procurement Notes

Verify the manufacturer designation carefully, as some listings may incorrectly attribute this part to Texas Instruments while official sources identify FTS as the producer. Confirm the HC-49S package type and 18 pF load capacitance requirements match your circuit design. Ensure compliance with RoHS standards if environmental regulations apply to your assembly process. Cross-reference the ±30ppm tolerance against your system's jitter and phase noise specifications to guarantee operational reliability.

Crystals Selection Notes

Select this component when a fixed 54 MHz reference is required with moderate stability needs. The HC-49S package offers a balance between size and thermal mass, suitable for general-purpose applications. Consider the 60 Ohm ESR value when designing the oscillator circuit to ensure proper startup and sustained oscillation. This part is appropriate for cost-sensitive designs where ±30ppm frequency drift over temperature is acceptable within the system budget.

Crystals Part Context

This crystal belongs to the broader category of MHz crystals used in timing applications. It serves as a passive frequency-determining element in oscillator circuits. Unlike active oscillators, it requires an external driver circuit to generate a square wave output. Its primary role is to define the base frequency for digital logic, ensuring synchronized data transmission and processing across connected components in embedded systems.

Crystals Replacement Considerations

Direct substitutes must match the 54 MHz frequency, HC-49S package, and ±30ppm tolerance. Verify that any alternative component maintains the same 18 pF load capacitance and similar ESR characteristics to prevent frequency pulling or startup failures. Check for pin compatibility and mounting style differences before integrating replacements into existing PCB footprints.
