Oscillators Procurement Notes

Verify the specific suffix 'A' in the part number against official datasheets to confirm the 3.3V supply requirement, as variants like 'B' may indicate different voltage levels. Ensure the 4-SMD footprint matches the target PCB layout. Confirm that the ±20 ppm stability meets system clock accuracy requirements before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a 19.66 MHz CMOS signal is required with low power consumption under 3.3V operation. Consider the ±20 ppm stability for general timing applications rather than high-precision synchronization. Evaluate the 4-SMD package size constraints against available board space. Verify compatibility with the system's enable/disable logic levels to ensure proper control functionality.

Oscillators Part Context

This model belongs to the SX7M series of surface-mount crystal oscillators from Shenzhen SCTF Electronics.
