Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact pinout configuration and tolerance grades. Ensure that the selected variant matches the required operating temperature range and supply voltage constraints for the target application environment. Cross-reference the datasheet revision date to guarantee compatibility with current design standards and regulatory compliance requirements.

Oscillators Selection Notes

Select this component when a low-profile surface-mount solution is required for timekeeping applications. Evaluate the 200 µA supply current against battery life requirements for portable designs. Confirm that the 1.8V minimum supply voltage aligns with the system's power rail availability. Consider the ±20 ppm stability sufficient for general real-time clock functions rather than high-precision metrology.

Oscillators Part Context

This oscillator belongs to the TSL series of surface-mount crystal oscillators from Transko Electronics. The series provides various frequency options and package sizes tailored for consumer electronics and industrial applications. The TSL22 model specifically targets space-constrained designs requiring reliable low-frequency timing signals with minimal power consumption.

Oscillators Replacement Considerations

Direct substitutes must match the 32.768 kHz frequency, HCMOS output type, and 4-SMD package dimensions. Verify equivalent supply voltage ranges and enable/disable functionality before integration.
