RIT2016C

The low power TCXO RIT2016C employs an analogue ASIC for the oscillator and a high order temperature compensation circuit in a

2.0 x 1.6 mm size package. The device can be placed in power down mode through a single input pin. During standard operation, power

consumption is minimised by operating down to a supply voltage of 1.2 V. The high stability, low power consumption, small footprint and

powerful compensation method makes RIT2016C a TCXO ideally suited for Smart Meters and Smartphone applications.
