RST2016AL

The low-power TCXO RST2016AL features an analogue ASIC-based oscillator and a high-order temperature compensation circuit within a

compact 2.0 x 1.6 mm package. The device offers enable/disable functionality, optimises power efficiency during standard operation, and

can operate at a supply voltage as low as 1.2 V.

The RST2016AL TCXO provides ±0.5 ppm frequency stability over a temperature range of -40°C to 85°C. With its low power consumption,

compact footprint, and advanced compensation technology, it is ideally suited for time and frequency reference applications across wireless

modules, GNSS positioning, consumer devices and IoT.

Parts should be shielded from drafts that cause unexpected thermal gradients. Temperature changes due to ambient air currents on the oscillator can lead

to short-term frequency drift.
