1.2mm²µPower, Low-Jitter, 3 & 5 ppm, 32.768 kHz Super-TCXO

Features

Applications

 32.768 kHz ±3 and ±5 ppm all-inclusive frequency stability

 World’s smallest TCXO Footprint: 1.2 mm²

 Smart watches, health and wellness monitors

 Ultra-accurate RTC reference clock

 Smart utility meters, E-meters

1.5 x 0.8 mm CSP

No external bypass cap required

 Internet-of-Things (IoT) with BLE

 Improved stability reduces system power with fewer network

timekeeping updates

 Low integrated phase jitter (IPJ) suitable for multiplying up for

portable audio: 2.5 ns_RMS

 Ultra-low power: 4.5 µA

 Operating supply voltage range: 1.62 V to 3.63 V

 Operating temperature ranges: -20°C to +70°C, -40°C to +85°C

 Pb-free, RoHS and REACH compliant

Electrical Specifications

Conditions: Min/Max limits are over temperature, Vdd = 1.8V ±10%, unless otherwise stated. Typicals are at 25°C and Vdd = 1.8V.
