18QHTF21-37.200-PD

Oscillators Overview

The 18QHTF21-37.200-PD is a 37.2 MHz crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates on a single 1.8V supply voltage and utilizes LVCMOS output logic. The device features a standby mode for power down functionality. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0mm x 1.6mm. This component is designed for applications requiring precise clock signals within a minimal footprint.

Oscillators Feature Summary

• LVCMOS output logic for standard digital interface compatibility
• Integrated standby mode enabling power down capability
• Compact 4-SMD no-lead surface mount package design

Oscillators Applications

• Portable electronic devices requiring low power consumption
• Embedded systems utilizing LVCMOS compatible processors
• Communication modules needing stable 37.2 MHz clock sources

Oscillators Procurement Notes

Verify the specific ordering suffix to confirm the presence of the standby function, as variants like OE indicate enable/disable control while PD indicates power down. Ensure the package type matches the required PCB footprint. Confirm that the 1.8V supply voltage aligns with the target system's power rails before procurement.

Oscillators Selection Notes

Select this component when a 37.2 MHz frequency is strictly required alongside a 1.8V operating voltage. The choice depends on the necessity for a small 2.0x1.6mm form factor. Consider the LVCMOS output level compatibility with downstream logic circuits. Evaluate if the standby feature meets power management requirements compared to continuous operation models.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which provides standard clock oscillators. The manufacturer specializes in quartz crystals and frequency control products. The 18QHTF21 prefix likely denotes the series and package style, while the numeric suffix specifies the frequency.

Oscillators Replacement Considerations

Direct substitutes include other 37.2 MHz LVCMOS oscillators in 4-SMD packages from different manufacturers. Verify pinout compatibility and voltage levels. Models such as those from Epson or NDK may serve as alternatives if electrical parameters match exactly.
