1553H-50.000K33DTSK

Overview

The 1553H-50.000K33DTSK is a 50 MHz standard HCMOS crystal oscillator manufactured by Suzhou Hangjing Elec & Tech Co., Ltd. It operates on a 3.3V supply voltage with a maximum current consumption of 20mA. The device features a frequency stability of ±15ppm across an operating temperature range of -40°C to +85°C. It utilizes a 4-SMD, no lead surface-mount package, specifically the 5032 footprint, designed for compact electronic applications requiring precise timing signals.

Feature Summary

• Generates a stable 50 MHz clock signal using HCMOS output logic levels
• Supports enable and disable control functionality for power management
• Operates reliably within a wide industrial temperature range from -40°C to +85°C
• Utilizes a compact 4-pin surface-mount package for efficient PCB layout

Applications

• Telecommunications equipment requiring precise signal processing
• In-vehicle systems and automotive electronics
• GPS navigation modules
• Satellite communication devices

Procurement Notes

Verify the specific datasheet provided by Suzhou Hangjing Elec & Tech Co., Ltd. to confirm pinout configurations and electrical tolerances before integration. Ensure that the 3.3V supply rail meets the maximum current requirements of 20mA. Cross-reference the 5032 package dimensions with your PCB footprint library to guarantee mechanical compatibility during assembly.

Selection Notes

Select this component when a 50 MHz HCMOS output is required in space-constrained designs. The ±15ppm stability suits general timing applications rather than high-precision metrology. Consider the -40°C to +85°C range for industrial or automotive environments. Verify that the 4-SMD no-lead package aligns with your manufacturing capabilities and reflow soldering profiles.

Part Context

This model belongs to the 1553H series of surface-mount crystal oscillators from Suzhou Hangjing. The series focuses on quartz frequency control components for consumer and industrial electronics. Similar variants in the lineup include different frequencies such as 2.048 MHz, maintaining consistent package and electrical characteristics while varying the output frequency.

Replacement Considerations

Direct substitutes must match the 50 MHz frequency, 3.3V supply, HCMOS output, and 4-SMD 5032 package. Verify that any alternative component offers comparable ±15ppm stability over the -40°C to +85°C range. Check for identical pin assignments and enable/disable control logic to ensure seamless circuit integration without redesign.
