IT2100L
-------
SMD Temperature Compensated Crystal Oscillators
-------
-------
SMD TCXO using analogue ASIC for compensation and two outputs capable of being
independently controlled with separate Enable/Disable pins for efficient power
management and clock distribution.
-------
Product description
-------
The I(V)T2100L series employs an analogue ASIC for the oscillator and a high order
temperature compensation circuit in a 2.0 x 1.6 mm size package. Each of two outputs can
be placed in power down mode through a dedicated input pin per output. During standard
operation, power consumption is minimized by operating down to a supply voltage of 1.8V.
The I(V)T2100L’s high stability, low power consumption, small footprint and powerful
compensation method makes it a TCXO ideally suited for demanding GPS mobile applications.
