RST2016A

The RST2016A employs an analogue ASIC for the oscillator 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 Temperature Compensated Crystal Oscillator (TCXO) provides a voltage control option (VCTCXO)

with a wide frequency range available from 13 to 52 MHz. Supply voltage options are 1.8 to 3.3 V.

The high stability RST2016A is designed for high-performance GNSS and communication applications where the required frequency stability

±0.5 ppm over operating temperature ranges from -40 to 85°C.
