Overview
The 18QHTF21-76.5432-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 76.5432 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a Standby (Power Down) function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.
Feature Summary
- LVCMOS output logic for digital interface compatibility
- Integrated standby mode for power reduction
- Compact surface-mount form factor
Applications
- General clock signal generation
- Digital circuit timing reference
- Embedded system clock sources
Procurement Notes
Verify the specific suffix 'PD' indicates the Standby (Power Down) functionality as documented. Confirm that the 1.8V supply voltage requirement aligns with the target system design. Ensure the 4-SMD No Lead package footprint matches the PCB layout specifications to guarantee proper assembly and electrical connection.
Selection Notes
Select this component when a precise 76.5432 MHz clock source is required with low-power standby capabilities. The choice depends on the necessity for LVCMOS signaling levels and the constraint of a 2.0x1.6mm package size. Consider the operating temperature range and supply voltage stability requirements before integration into the final design.
Part Context
This part belongs to the Mercury Electronics XO series, which provides standard frequency control solutions. The model number structure indicates the frequency, voltage, and package type. Mercury Electronics has been manufacturing frequency control products since 1973, establishing this component within their established portfolio of quartz-based oscillators.
Replacement Considerations
The 18QHTF21-76.5432-OE is an alternative variant from the same manufacturer. However, it lacks the Standby (Power Down) feature found in the -PD version. Verify if the enable/disable function of the OE variant meets the power management requirements if considering it as a substitute.
