Product Description
The PI6CX100-272 is a low-cost, high-performance 3.3V VCXO,
designed to replace expensive VCXO modules. The on-chip Volt-
age Controlled Crystal Oscillator accepts a 0 to 3.3V input voltage
to cause clocks to vary from -250 ppm to +150 ppm. This device
uses an inexpensive external pullable crystal at 27 MHz to produce
the same output frequency.
The PI6CX100-272 is designed for Set-Top Box applications.
