12.90327

Overview

The Geyer Electronic America, Inc. part number 12.90327 is a surface-mount crystal oscillator (XO) from the KXO-V94T series. It operates at a frequency of 48 MHz with HCMOS output and ±50ppm stability. The device supports a supply voltage range of -0.5V to 7V, with typical operation at 3.3V. Maximum supply current is 8mA, while disabled current is under 50µA. It features enable/disable functionality and functions within an operating temperature range of -40°C to 85°C. The component utilizes a 4-SMD, no-lead package measuring 3.20mm x 2.50mm x 0.80mm.

Feature Summary

• HCMOS output interface for standard digital logic compatibility
• Enable/Disable control function for power management
• Surface mount construction in a compact 4-SMD no-lead package

Applications

• ASIC clocking tree signal conditioning
• MCU or MPU system clock generation
• FPGA timing reference support

Procurement Notes

Verify the specific ordering suffix required for your application needs, as packaging options may vary between tape and reel, cut tape, or Digi-Reel formats. Confirm that the 48 MHz frequency and 3.3V nominal supply align with your circuit design requirements before finalizing procurement. Ensure the KXO-V94T series designation matches your bill of materials to avoid substitution errors.

Selection Notes

Select this component when a 48 MHz HCMOS clock source is required for embedded systems. The wide supply voltage tolerance allows flexibility in power rail selection. Consider the physical dimensions of the 3.20mm x 2.50mm footprint for PCB layout constraints. The enable pin feature is suitable for applications requiring dynamic power saving modes.

Part Context

This oscillator belongs to the KXO-V94T series designed by Geyer Electronic America, Inc. These devices are precision quartz frequency control components intended for use in ASICs, MCUs, MPUs, and FPGAs. The series provides reliable clocking tree signal conditioning with stable performance across industrial temperature ranges.

Replacement Considerations

Direct substitutes must match the 48 MHz frequency, HCMOS output, and 4-SMD package. Verify equivalent stability and voltage specifications. Cross-reference with other KXO-V94T variants if different frequencies are acceptable.
