18QHTF21-60.8875-PD

Overview

The 18QHTF21-60.8875-PD is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 60.8875 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a standby function for power down control. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. The component supports an operating temperature range of -40°C to 85°C and maintains a frequency stability of ±50ppm.

Feature Summary

• Supports standby mode for power management
• Compact surface-mount package design
• LVCMOS output compatibility

Applications

• General clock signal generation
• Embedded system timing
• Consumer electronics circuits

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure that the 1.8V supply rail is stable within the specified operating temperature range to maintain the stated frequency stability. Confirm that the PCB footprint matches the 2.0x1.6mm SMD package dimensions to avoid assembly issues during manufacturing.

Selection Notes

Select this component when a low-voltage, small-footprint clock source is required for digital logic interfaces. The LVCMOS output ensures compatibility with standard CMOS inputs. Consider the ±50ppm stability specification against your system's jitter and phase noise requirements. The wide industrial temperature range makes it suitable for environments with significant thermal variations.

Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies and package options. The 'PD' suffix typically indicates the presence of a power-down or standby pin functionality. These oscillators are designed for applications requiring precise timing signals in space-constrained electronic devices.

Replacement Considerations

Direct replacements must match the 60.8875 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify that any substitute component supports the same standby functionality and meets the -40°C to 85°C operating temperature range. Check for equivalent frequency stability specifications.
