VT73127
27 MHz 3.3V VCXO with Output Enable
Applications
•= Crystal-driven clock source
General Description
The Vaishali VT73127 is a single-chip, low-jitter Voltage-Controlled-Crystal-Oscillator. The device accepts
a 27 MHz, 20 pF crystal input, and produces a low jitter output at the same frequency. The output is
enabled when OE is logic HIGH and goes into high impedance state when OE is logic LOW. A 0 to 3.0V
control signal is used to fine tune the output clock frequency in the ±100ppm range.
Features
•= 3.3V operating voltage
•= Uses inexpensive pullable crystals
•= 12mA drive capability at TTL levels
•= On-chip oscillator with 200 ppm pull range (±100 ppm)
•= Active High output enable
•= Die only
