Description
The PI6CX100-00 is a low-cost, high-performance, 3.3V, VCXO
available in discrete IC form with external quartz cryatal. The on-
chip Voltage Controlled Crystal Oscillator accepts a 0V to 3.3V
input voltage that pulls the output clock frequency by ±120ppm.
This device operates with an external quartz crystal specified to
achieve the desired performance.
The PI6CX100-00 is designed for General Purpose applications,
supporting operating frequencies between 19.44 and 40 MHz.
