Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required load capacitance and tolerance specifications. Confirm that the 4-SMD package footprint matches the target PCB layout constraints. Check for any recent product lifecycle notifications or obsolescence warnings from TXC Corporation prior to finalizing procurement plans.

Crystals Selection Notes

Select this component when a 27.12 MHz reference is required for applications demanding ±30 ppm stability across industrial temperatures. Ensure the circuit design accommodates the specified 20 pF load capacitance to maintain accurate frequency performance. Verify that the 60 Ohm ESR value aligns with the oscillator circuit's drive level requirements to prevent over-driving the crystal.

Crystals Part Context

This part belongs to the 7M series of crystals from TXC Corporation, which are characterized by their compact 3.2 x 2.5 mm SMD form factor. The series is engineered for general-purpose timing applications where space efficiency and reliable frequency stability are prioritized. It serves as a standard passive component for establishing precise clock signals in embedded systems.

Crystals Replacement Considerations

Direct substitutes include other 27.12 MHz crystals with identical 20 pF load capacitance, ±30 ppm tolerance, and 4-SMD no-lead packaging. Cross-reference with manufacturers offering equivalent 3.2 x 2.5 mm footprints and matching thermal ratings.
