MQF576P25-53.000-1.0/-40+85

Oscillators Overview

The MQF576P25-53.000-1.0/-40+85 is a surface-mount Temperature Compensated Crystal Oscillator (TCXO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 53.000 MHz with a frequency stability of ±1 ppm across an operating temperature range of -40°C to +85°C. The device utilizes a 2.5V supply voltage and features LVPECL output mode. Maximum supply current is specified at 36 mA. The component is housed in a compact SMD package measuring 7.0 x 5.0 x 2.5 mm with six pads, designed for high-performance timing applications requiring low phase jitter and stable frequency generation.

Oscillators Procurement Notes

Verify the specific output voltage level and load capacitance requirements against the target circuit design before procurement. Confirm that the LVPECL output interface matches the receiving component's input specifications. Ensure the operating temperature range of -40°C to +85°C aligns with the environmental conditions of the final application. Cross-reference the pinout diagram from the official datasheet to validate PCB layout compatibility.

Oscillators Selection Notes

Select this component when a stable 53 MHz reference signal is required with tight tolerance constraints. The LVPECL output offers superior noise immunity compared to other logic families, making it suitable for high-speed digital interfaces. Consider the 2.5V supply requirement for power budgeting. The ±1 ppm stability ensures minimal drift over temperature variations, critical for maintaining data integrity in synchronous communication protocols.

Oscillators Part Context

This part belongs to the MQF576 series of QuikXO TCXOs from Mercury Electronics. The series includes variants with different frequencies, supply voltages (2.5V or 3.3V), and output types (LVPECL or LVDS). The 'P' suffix typically denotes LVPECL output, while 'D' may indicate LVDS. The model number encodes the frequency, voltage, stability, and temperature range, allowing for easy identification within the product family.

Oscillators Replacement Considerations

Direct replacements must match the 53.000 MHz frequency, ±1 ppm stability, 2.5V supply, and LVPECL output. Verify mechanical compatibility with the 7.0x5.0x2.5mm SMD package. Check if alternative suppliers offer equivalent performance metrics. Ensure thermal characteristics and aging specifications meet the original design requirements.
