NCD2400M Wide Capacitance Range, Non-volatile
I
Digital Programmable Capacitor
NTEGRATED CIRCUITS DIVISION
Features Description •
DC to 150MHz frequency range The NCD2400M is a dedicated electronic calibrator for
•
512-state digital programmable capacitor oscillators, with reliable performance at 105ºC as
•
Series or shunt configuration required by OCXO applications. Cshunt = 12.5pF to 194pF (15.5:1 tuning ratio) in This product can be used in series or shunt discrete 355fF steps configuration to support a wide variety of tuning circuit Cseries = 1.7pF to 194pF in discrete 376fF steps topologies.
•
2-wire (I2C Fast-mode compatible) serial interface Digitally controlled capacitance trimming information is
•
EEPROM non-volatile memory
•
Wide power supply range (2.5V to 5.5V) communicated via a 2-wire, I2C Fast-mode compatible
•
Operation ambient temperature to 105ºC interface. The preferred power-up default capacitance
•
2 x 2 x 0.65 mm 6-pin DFN package value can be stored in the internal, re-programmable, non-volatile memory.
