Description
The NCD2400M is a dedicated electronic calibrator for
oscillators, with reliable performance at 105ºC as
required by OCXO applications.
This product can be used in series or shunt
configuration to support a wide variety of tuning circuit
topologies.
Digitally controlled capacitance trimming information is
communicated via a 2-wire, I2C Fast-mode compatible
interface. The preferred power-up default capacitance
value can be stored in the internal, re-programmable,
non-volatile memory.
