LFSPXO073707

Overview

The LFSPXO073707 is a standard CMOS clock oscillator manufactured by IQD Frequency Products. It operates at a nominal frequency of 32.768 kHz with a supply voltage of 1.8V. The device features an enable/disable function and is housed in a compact 4-SMD, no-lead package measuring 2.00mm x 1.60mm x 0.80mm. It exhibits a frequency stability of ±100ppm across the industrial temperature range of -40°C to +125°C. Maximum supply current is specified at 200µA.

Feature Summary

• Integrated enable and disable control functionality for power management
• Hermetically sealed ceramic package with metal seam-welded lid ensuring high reliability
• Compact surface-mount footprint suitable for space-constrained designs

Applications

• Real-time clock (RTC) circuits in microcontrollers
• Industrial timing applications requiring wide temperature tolerance
• Low-power embedded systems utilizing 1.8V logic levels

Procurement Notes

Verify the specific suffix against the manufacturer's latest documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status and lead-free soldering compatibility prior to integration. Ensure the design supports the required 1.8V supply rail and accounts for the maximum 200µA current consumption during active operation.

Selection Notes

Select this component when a precise 32.768 kHz reference is needed for RTC synchronization in harsh environments. The ±100ppm stability over -40°C to +125°C makes it suitable for industrial use where consumer-grade oscillators may fail. The enable pin allows for dynamic power reduction, which is critical for battery-operated devices requiring extended standby times.

Part Context

This part belongs to the IQXO-404 series from IQD Frequency Products. It is designed as a direct replacement for legacy components in low-frequency timing applications. The series emphasizes robustness through its ceramic construction, distinguishing it from plastic-packaged alternatives that may lack long-term stability in humid or extreme thermal conditions.
