This 32.768 kHz MEMS super-TCXO provides ±3 ppm all-inclusive frequency stability in a 1.5 x 0.8 mm chip-scale package. It is optimized for battery-powered designs and draws 4.5 µA typical with 2.5 ns RMS integrated phase jitter and 300 ms maximum startup time. The device provides an LVCMOS clock output with 45% to 55% duty cycle and supports the commercial temperature range from -20°C to +70°C for this ordering code. It is lead-free and marked compliant with RoHS and REACH requirements.
