RST2016H

The RST2016H is a high temperature TCXO (Temperature Compensated Crystal Oscillator) / VCTCXO (Voltage Controlled Temperature

Compensated Crystal Oscillator). It is designed for high-performance automotive and communication applications where a frequency stability

of ±0.5 ppm is required over an operating temperature range of -40 to 105°C.

The RST2016H has an analogue ASIC and a high-order temperature compensation circuit in a small font factor 2.0 x 1.6 x 0.7 mm package.

This low-power SMD TCXO provides a voltage control option of VCTCXO, with a wide frequency range available from 10 to 52 MHz. Supply

voltage options are 1.8 to 3.3 V.
