18QHTF21-11.0896-PD

Overview

The 18QHTF21-11.0896-PD is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 11.0896 MHz and utilizes LVCMOS output logic. The component requires a supply voltage of 1.8V and features a Standby (Power Down) function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Supports Low Voltage Complementary Metal-Oxide-Semiconductor (LVCMOS) output logic levels
• Includes standby capability to reduce power consumption when not in active use
• Designed for surface-mount integration using a leadless four-terminal SMD package

Applications

• General purpose timing circuits requiring standard clock signals
• Embedded systems utilizing low-voltage digital interfaces
• Portable electronic devices where space constraints require small form factors

Procurement Notes

Verify the specific ordering suffix PD against the manufacturer's current documentation to ensure correct packaging and handling specifications. Confirm that the 1.8V supply requirement aligns with the target system's power rails. Check for any RoHS compliance declarations or material disclosures required for the intended application environment. Ensure the operating temperature range meets the environmental conditions of the final assembly.

Selection Notes

Select this component when a precise 11.0896 MHz reference is needed for LVCMOS-compatible digital logic. The choice is driven by the requirement for a low-profile 2.0x1.6 mm footprint suitable for dense PCB layouts. Consider the standby feature if power efficiency during idle states is a critical design parameter. Validate that the 1.8V operating voltage matches the available core voltage in the target circuit architecture.

Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series typically offers various frequencies within a consistent 1.8V LVCMOS format. The 11.0896 MHz variant serves as a specific timing solution distinct from other frequencies in the same physical package family, such as 8.96 MHz or 8.000 MHz options.

Replacement Considerations

Direct substitutes must match the 11.0896 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package dimensions. Cross-reference with other manufacturers offering identical pinout and electrical characteristics to ensure functional interchangeability without board redesign.
