12.89004

Crystals Overview

The Geyer Electronic America, Inc. model 12.89004 is a quartz crystal component designed for precision frequency control applications. It operates at a fundamental frequency of 25 MHz with a specified tolerance of ±100ppm. The device features a load capacitance of 16pF and an equivalent series resistance (ESR) of 60 Ohms. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly processes. This component serves as a critical element in clocking tree signal conditioning for digital logic circuits.

Crystals Feature Summary

• Provides precise frequency generation for ASIC, MCU, MPU, or FPGA clocking trees
• Utilizes KX-9B quartz technology for signal conditioning stability
• Designed for surface-mount integration via leadless SMD packaging

Crystals Applications

• Clocking tree signal conditioning for ASICs
• Frequency reference for Microcontroller Units (MCUs)
• Clock source for Microprocessor Units (MPUs)
• Timing reference for Field Programmable Gate Arrays (FPAs)

Crystals Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your circuit design before ordering. Confirm that the 4-SMD no-lead package dimensions align with your PCB footprint constraints. Ensure the ±100ppm tolerance meets the system's jitter and accuracy specifications. Cross-reference the manufacturer's latest datasheet to confirm current availability and any potential supply chain delays associated with high-demand periods.

Crystals Selection Notes

Select this component when a stable 25 MHz reference is required for digital logic families. The 16pF load capacitance must match the oscillator circuit design to ensure accurate frequency output. Consider the 60 Ohm ESR for drive level sensitivity and power consumption limits. The leadless SMD form factor is ideal for automated pick-and-place manufacturing and space-constrained layouts.
