ASEK-32.768KHZ-L-R-T Description

Short technical summary and product information.

The Abracon ASEK-32.768KHZ-L-R-T is a surface-mount crystal oscillator (XO) that provides a precise 32.768 kHz output with CMOS logic levels. It is designed for low-power applications requiring a stable clock reference.

 

Key electrical specifications include a nominal supply voltage of 3.3V ±10%, typical supply current of 1.7 mA (3.5 mA max), and frequency stability of ±25 ppm over the full operating temperature range of -40°C to +85°C. The output is CMOS with 40/60% symmetry and typical rise/fall times of 40 ns. The device features an enable/disable (tri-state) function: logic high or open enables oscillation, logic low places the output in high impedance.

 

The oscillator is housed in a compact 4-SMD, No Lead ceramic package measuring 3.20 mm x 2.50 mm x 1.20 mm, suitable for space-constrained designs. It is RoHS3 compliant and lead-free, and is supplied in tape and reel packaging with 1,000 pieces per reel.
