1521H-32K768AWVDZSK

Overview

The 1521H-32K768AWVDZSK is a standard crystal oscillator manufactured by Suzhou Hangjing Elec&Tech Co., Ltd. It operates at a frequency of 32.768 kHz and utilizes HCMOS output logic. The device supports a supply voltage range of 1.8V to 3.3V and features enable/disable control functionality. It is housed in a compact 4-SMD, no lead package with dimensions of 2016.

Feature Summary

• Provides stable clock signals using HCMOS output technology
• Supports flexible power supply voltages from 1.8V to 3.3V
• Includes enable and disable control capabilities for power management

Applications

• Real-time clock circuits
• Low-frequency timing references
• Portable electronic devices requiring low power consumption

Procurement Notes

Verify the specific ordering suffix ZSK against official manufacturer documentation to confirm pinout configuration and tolerance specifications. Ensure compatibility with target system voltage levels within the 1.8V to 3.3V range before integration. Cross-reference the package type 2016 with PCB footprint requirements to prevent assembly errors.

Selection Notes

Select this component when a precise 32.768 kHz reference is required for timekeeping or low-speed synchronization. The HCMOS interface ensures compatibility with standard digital logic families. Consider the enable/disable feature if power efficiency is critical for battery-operated applications.

Part Context

This oscillator belongs to the 1521H series of quartz frequency control units produced by Suzhou Hangjing. The series specializes in compact surface-mount oscillators designed for consumer electronics and industrial applications requiring reliable frequency stability.

Replacement Considerations

Direct substitutes must match the 32.768 kHz frequency, HCMOS output, 2016 package, and 1.8V-3.3V voltage range. Verify electrical parameters and pin assignments with alternative manufacturers to ensure functional equivalence.
