18QHTF57-9.740-PD

Oscillators Overview

The 18QHTF57-9.740-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 9.74 MHz with an output logic format of LVCMOS. The device requires a supply voltage of 1.8V and features a standby mode for power down functionality. Frequency stability is rated at ±50ppm over the operating temperature range of -40°C to 85°C. The component is housed in a compact 4-SMD, No Lead package.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V with integrated power-down capability
• Delivers LVCMOS output signals suitable for digital interfacing
• Maintains frequency stability within ±50ppm across industrial temperature ranges

Oscillators Applications

• Clock generation for embedded systems
• Timing reference for communication interfaces
• Power management circuits requiring precise timing

Oscillators Procurement Notes

Verify the specific suffix 'PD' indicates the power-down feature as documented. Confirm the 1.8V supply requirement matches the target circuit design. Ensure the 4-SMD no-lead package dimensions align with PCB footprint constraints. Check lifecycle status for long-term availability assurance.

Oscillators Selection Notes

Select this model when a 9.74 MHz clock source is required with low power consumption. The LVCMOS interface ensures compatibility with standard digital logic families. Consider the ±50ppm stability specification against system jitter requirements. The wide temperature range supports operation in demanding environments.

Oscillators Part Context
