QTM750-32.768MBD-T

Oscillators Overview

The QTM750-32.768MBD-T is a standard clock oscillator manufactured by TXC Corporation, distributed under the FTS brand designation in certain contexts. This surface-mount device utilizes CMOS output technology and operates at a nominal frequency of 32.768 MHz. It features a frequency stability of ±25 ppm and requires a supply voltage of 3.3 V. The component is housed in a 4-pin CSMD package with dimensions of 7.0 x 5.0 mm. It is designed for operation within an industrial temperature range of -40°C to +85°C.

Oscillators Feature Summary

• CMOS output interface for digital logic compatibility
• Industrial temperature range capability from -40°C to +85°C
• Compact 4-pin surface mount package design

Oscillators Applications

• Real-time clock circuits in embedded systems
• Microcontroller system timing references
• Low-frequency signal generation in consumer electronics

Oscillators Procurement Notes

Verify the manufacturer origin carefully, as the part number is primarily associated with TXC Corporation. Confirm that the specific suffix corresponds to the 3.3V supply and ±25 ppm stability requirements. Ensure the package type matches the 7.0x5.0mm footprint specifications. Cross-reference datasheets to confirm operational temperature ranges align with application needs before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a precise 32.768 MHz reference is required for timekeeping or low-speed synchronization. The CMOS output ensures direct interfacing with standard digital logic without additional buffering. Consider the ±25 ppm stability for applications tolerant of minor frequency drift over temperature variations. The 3.3V operating voltage suits modern low-power digital designs.

Oscillators Part Context

This oscillator belongs to the QTM750 series, which provides standard clock signals in compact surface-mount packages. The series offers various frequency options and supply voltages to accommodate different system requirements. The 32.768 MHz variant is specifically optimized for real-time clock applications due to its binary-compatible frequency division properties.

Oscillators Replacement Considerations

The QTM750-32.768MBE-T is a documented alternative within the same series, offering ±50 ppm stability instead of ±25 ppm. Verify pinout compatibility and electrical parameters before substitution. Other variants in the QTM750 family may differ in supply voltage or package dimensions.
