ASTMTXK-32.768KHZ-LY-T10

Oscillators Overview

The ASTMTXK-32.768KHZ-LY-T10 is a MEMS-based TCXO operating at 32.768 kHz with LVCMOS output. It features a compact 1.54x0.84x0.6 mm package and supports 1.5V to 3.63V supply. The LY suffix indicates ±10ppm temperature stability (0~70°C) and ±13ppm total stability (-40~85°C). Core current is max 1.52uA, with total current under 2uA. It includes internal power filtering for ±150mV noise rejection, eliminating external bypass capacitors. Start-up time is approximately 300ms at room temperature.

Oscillators Feature Summary

Oscillators Procurement Notes

Verify the specific suffix 'LY' corresponds to the required temperature stability class of ±10ppm over 0~70°C and ±13ppm total over -40~85°C. Confirm that the LVCMOS output format matches the target MCU interface. Ensure the 1.5V minimum supply voltage aligns with the system's lowest operating voltage during discharge cycles.

Oscillators Selection Notes

Select this component when PCB area is constrained below standard crystal solutions. Choose the LY grade for applications requiring tighter frequency stability than the J grade but not the highest G grade precision. Consider the 300ms start-up time for systems requiring rapid wake-up from deep sleep modes.

Oscillators Part Context

Part of the ASTMTXK series, designed specifically for space-constrained portable electronics. Utilizes MEMS resonators instead of traditional quartz crystals to achieve smaller dimensions while maintaining stable oscillation frequencies for timing applications.

Oscillators Replacement Considerations

ASTMTXK-32.768KHZ-LJ-T10 offers similar form factor with lower stability (±20ppm/±22ppm). ASTMTXK-32.768KHZ-LG-T10 provides higher stability (±5ppm/±10ppm). Verify pinout and electrical characteristics before substitution.
